Because of its extreme rarity, there have been no controlled clinical trials of treatment regimens for FA and, as a result, there are no evidence-based treatment guidelines. Complete surgical resection is the treatment of choice in FA, as it is in nearly all forms of lung cancer.

Anecdotal reports suggest that FA is rarely highly sensitive to cytotoxic drugs or radiation. Case reports suggest that chemotherapy with UFT may be useful in FA.

In ES-SCLC, combination chemotherapy is the standard of care, with radiotherapy added only to palliate symptoms such as dyspnea, pain from liver or bone metastases, or for treatment of brain metastases, which, in small-cell lung carcinoma, typically have a rapid, if temporary, response to whole brain radiotherapy.

Combination chemotherapy consists of a wide variety of agents, including cisplatin, cyclophosphamide, vincristine and carboplatin. Response rates are high even in extensive disease, with between 15% and 30% of subjects having a complete response to combination chemotherapy, and the vast majority having at least some objective response. Responses in ES-SCLC are often of short duration, however.

If complete response to chemotherapy occurs in a subject with SCLC, then prophylactic cranial irradiation (PCI) is often used in an attempt to prevent the emergence of brain metastases. Although this treatment is often effective, it can cause hair loss and fatigue. Prospective randomized trials with almost two years follow-up have not shown neurocognitive ill-effects. Meta-analyses of randomized trials confirm that PCI provides significant survival benefits.

A very large number of clinical trials have been conducted in "pure" SCLC over the past several decades. As a result, evidence-based sets of guidelines for treating monophasic SCLC are available. While the current set of SCLC treatment guidelines recommend that c-SCLC be treated in the same manner as "pure" SCLC, they also note that the evidence supporting their recommendation is quite weak. It is likely, then, that the optimum treatment for patients with c-SCLC remains unknown.

The current generally accepted standard of care for all forms of SCLC is concurrent chemotherapy (CT) and thoracic radiation therapy (TRT) in LD, and CT only in ED. For complete responders (patients in whom all evidence of disease disappears), prophylactic cranial irradiation (PCI) is also given. TRT serves to increase the probability of total eradication of residual locoregional disease, while PCI aims to eliminate any micrometastases to the brain.

Surgery is not often considered as a treatment option in SCLC (including c-SCLC) due to the high probability of distant metastases at the time of diagnosis. This paradigm was driven by early studies showing that the administration of systemic therapies resulted in improved survival as compared to patients undergoing surgical resection. Recent studies, however, have suggested that surgery for highly selected, very early-stage c-SCLC patients may indeed improve outcomes. Other experts recommend resection for residual masses of NSCLC components after complete local tumor response to chemotherapy and/or radiotherapy in c-SCLC.

Although other combinations of drugs have occasionally been shown to be noninferior at various endpoints and in some subgroups of patients, the combination of cisplatin or carboplatin plus etoposide or irinotecan are considered comparable first-line regimens for SCLC. For patients who do not respond to first line therapy, or who relapse after complete remission, topotecan is the only agent which has been definitively shown to offer increased survival over best supportive care (BSC), although in Japan amirubicin is considered effective as salvage therapy.

Importantly, c-SCLC is usually much more resistant to CT and RT than "pure" SCLC. While the mechanisms for this increased resistance of c-SCLC to conventional cytotoxic treatments highly active in "pure" SCLC remain mostly unknown, recent studies suggest that the earlier in its biological history that a c-SCLC is treated, the more likely it is to resemble "pure" SCLC in its response to CT and RT.

Early stage disease is treated surgically. Targeted therapy is available for lung adenocarcinomas with certain mutations. Crizotinib is effective in tumors with fusions involving ALK or ROS1, whereas gefitinib, erlotinib, and afatinib are used in patients whose tumors have mutations in EGFR.

NSCLCs are usually "not" very sensitive to chemotherapy and/or radiation, so surgery remains the treatment of choice if patients are diagnosed at an early stage. If patients have small, but inoperable tumors, they may undergo highly targeted, high intensity radiation therapy. New methods of giving radiation treatment allow doctors to be more accurate in treating lung cancers. This means less radiation affects nearby healthy tissues. New methods include Cyberknife and stereotactic body radiation therapy(SBRT). Certain patients deemed to be higher risk may also receive adjuvant (ancillary) chemotherapy after initial surgery or radiation therapy. There are a number of possible chemotherapy agents which can be selected however most will involve the platinum-based chemotherapy drug called cisplatin.

Other treatments include percutaneous ablation and chemoembolization. The most widely used ablation techniques for lung cancer are radiofrequency ablation, cryoablation, and microwave ablation. Ablation may be an option for patients whose tumors are near the outer edge of the lungs. Nodules less than 1 cm from the trachea, main bronchi, oesophagus and central vessels should be excluded from RFA given high risk of complications and frequent incomplete ablation. Additionally, lesions greater than 5 cm should be excluded and lesions 3 to 5 cm should be considered with caution given high risk of recurrence. As a minimally invasive procedure, it can be a safer alternative for patients who are poor candidates for surgery due to co-morbidities or limited lung function. A study comparing thermal ablation to sublobar resection as treatment for early stage NSCLC in older patients found no difference in overall survival of the patients. It is possible that RFA followed by radiation therapy has a survival benefit due to synergysm of the two mechanisms of cell destruction.

A wide variety of chemotherapies options exist for used in advanced (metastatic) NSCLC. These agents include both traditional chemotherapies like cisplatin which indiscriminately target all rapidly dividing cells as well as newer targeted agents which are more tailored to specific genetic aberrations found within a patient's tumor. At present there are two genetic markers which are routinely profiled in NSCLC tumors to guide further treatment decision making: mutations within EGFR and Anaplastic Lymphoma Kinase. There are also a number of additional genetic markers which are known to be mutated within NSCLC and may impact treatment in the future, including BRAF (gene), HER2/neu and KRAS.

Thermal ablations i.e. radiofrequency ablation, cryoablation, microwave ablation are appropriate for palliative treatment of tumor-related symptoms or recurrences within treatment fields. Patients with severe pulmonary fibrosis and severe emphysema with a life expectancy <1 year should be considered poor candidates for this treatment.

In cases of LS-SCLC, combination chemotherapy (often including cyclophosphamide, cisplatinum, doxorubicin, etoposide, vincristine and/or paclitaxel) is administered together with concurrent chest radiotherapy (RT).

Chest RT has been shown to improve survival in LS-SCLC.

Exceptionally high objective initial response rates (RR) of between 60% and 90% are seen in LS-SCLC using chemotherapy alone, with between 45% and 75% of individuals showing a "complete response" (CR), which is defined as the disappearance of all radiological and clinical signs of tumor. However, relapse rate remains high, and median survival is only 18 to 24 months.

Because SCLC usually metastasizes widely very early on in the natural history of the tumor, and because nearly all cases respond dramatically to chemotherapy and/or radiotherapy, there has been little role for surgery in this disease since the 1970s. However, recent work suggests that in cases of small, asymptomatic, node-negative SCLC's ("very limited stage"), surgical excision may improve survival when used prior to chemotherapy ("adjuvant chemotherapy").

Because LCLC-RP is so rare, no clinical trials have ever been conducted that specifically address treatment of this lung cancer variant. Because LCLC-RP is considered a form of non-small cell lung carcinoma (NSCLC), most physicians adhere to published NSCLC treatment guidelines in rhabdoid carcinoma cases. When possible, radical surgical resection with curative intent is the primary treatment of choice in early stage NSCLC's, and can be administered with or without adjuvant, neoadjuvant, or palliative chemotherapy and/or radiotherapy, depending on the disease stage and performance status of the individual patient.

In numerous clinical trials conducted in NSCLC, several different platinum-based chemotherapy regimens have been shown to be more-or-less equally effective. LCLC's, as a subtype of NSCLC, have traditionally been included in many of these clinical trials, and have been treated like other NSCLC's. More recent trials, however, have shown that some newer agents may have particular effectiveness in prolonging survival of LCLC patients. Pemetrexed, in particular, has shown significant reduction in the hazard ratio for death when used in patients with LCLC. Taxane-based (paclitaxel, docetaxel) chemotherapy was shown to induce a complete and sustained response in a liver metastasis in a case of LCC-RP. A later-appearing metastasis within mediastinal lymph nodes in the same case also showed a durable response to a taxane alone.

There have also been reports of rhabdoid carcinomas expressing vascular endothelial growth factor (VEGF), suggesting that targeted molecular therapy with VEGF blocking monoclonal antibodies such as bevacizumab may be active in these variants. However, evidence suggests that caution must be used when treating a cavitated rhabdoid tumor, one that contains significant components of squamous cell differentiation, or large tumors with containing major blood vessels, due to the potential high risk of life-threatening pulmonary hemorrhage.

A recent study reported a case wherein 2 courses of adjuvant therapy with cisplatin and paclitaxel, followed by oral gefitinib, were used after complete resection. The patient had had no recurrence 34 months later.

As large-volume LCLC-RP may show significant central necrosis and cavitation, prudence dictates that oncologists use extreme caution if contemplating the therapeutic use of bevacizumab, other anti-VEGF compounds, or anti-angiogenesis agents in general, which have been associated with a greatly increased risk of severe hemorrhage and hemoptysis that may be quickly fatal in cavatated pulmonary squamous cell carcinomas. Similar elevated risks have also been noted in tumors located near, or containing, large blood vessels.,

Complete radical surgical resection is the treatment of choice for EMECL, and in most cases, results in long-term survival or cure.

The treatment of choice in any patient with BAC is complete surgical resection, typically via lobectomy or pneumonectomy, with concurrent ipsilateral lymphadenectomy.

Non-mucinous BACs are highly associated with classical EGFR mutations, and thus are often responsive to targeted chemotherapy with erlotinib and gefitinib. K-ras mutations are rare in nm-BAC.

Mucinous BAC, in contrast, is much more highly associated with K-ras mutations and wild-type EGFR, and are thus usually insensitive to the EGFR tyrosine kinase inhibitors. In fact, there is some evidence that suggests that the administration of EGFR-pathway inhibitors to patients with K-ras mutated BACs may even be harmful.

In recent years, several new types of "molecularly targeted" agents have been developed and used to treat lung cancer. While a very large number of agents targeting various molecular pathways are being developed and tested, the main classes and agents that are now being used in lung cancer treatment include:

- Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs):

- Erlotinib (Tarceva)

- Gefitinib (Iressa)

- Cetuximab (Erbitux)

- Inhibitors of vascular endothelial growth factor (VEGF)

- Bevacizumab (Avastin)

- Inhibitors of folate metabolism

- Pemetrexed (Alimta)

To date, most clinical trials of targeted agents, alone and in combination with previously tested treatment regimens, have either been ineffective in SCLC or no more effective than standard platinum-based doublets. While there have been no randomized clinical trials of targeted agents in c-SCLC, some small case series suggest that some may be useful in c-SCLC. Many targeted agents appear more active in certain NSCLC variants. Given that c-SCLC contains components of NSCLC, and that the chemoradioresistance of NSCLC components impact the effectiveness of c-SCLC treatment, these agents may permit the design of more rational treatment regimens for c-SCLC.

EGFR-TKI's have been found to be active against variants exhibiting certain mutations in the EGFR gene. While EGFR mutations are very rare (<5%) in "pure" SCLC, they are considerably more common (about 15–20%) in c-SCLC, particularly in non-smoking females whose c-SCLC tumors contain an adenocarcinoma component. These patients are much more likely to have classical EGFR mutations in the small cell component of their tumors as well, and their tumors seem to be more likely to respond to treatment with EGFR-TKI's. EGFR-targeted agents appear particularly effective in papillary adenocarcinoma, non-mucinous bronchioloalveolar carcinoma, and adenocarcinoma with mixed subtypes.

The role of VEGF inhibition and bevacizumab in treating SCLC remains unknown. Some studies suggest it may, when combined with other agents, improve some measures of survival in SCLC patients and in some non-squamous cell variants of NSCLC.

Pemetrexed has been shown to improve survival in non-squamous cell NSCLC, and is the first drug to reveal differential survival benefit in large cell lung carcinoma.

Interestingly, c-SCLC appear to express female hormone (i.e. estrogen and/or progesterone) receptors in a high (50–67%) proportion of cases, similar to breast carcinomas. However, it is at present unknown whether blockade of these receptors affects the growth of c-SCLC.

Several drugs that target molecular pathways in lung cancer are available, especially for the treatment of advanced disease. Erlotinib, gefitinib and afatinib inhibit tyrosine kinase at the epidermal growth factor receptor. Denosumab is a monoclonal antibody directed against receptor activator of nuclear factor kappa-B ligand. It may be useful in the treatment of bone metastases.

The prognosis of patients with FA as a whole is considered to be better than that of most other forms of non-small cell carcinoma, including biphasic pulmonary blastoma.

Chemotherapy is the only treatment for mesothelioma that has been proven to improve survival in randomised and controlled trials. The landmark study published in 2003 by Vogelzang and colleagues compared cisplatin chemotherapy alone with a combination of cisplatin and pemetrexed (brand name Alimta) chemotherapy in patients who had not received chemotherapy for malignant pleural mesothelioma previously and were not candidates for more aggressive "curative" surgery. This trial was the first to report a survival advantage from chemotherapy in malignant pleural mesothelioma, showing a statistically significant improvement in median survival from 10 months in the patients treated with cisplatin alone to 13.3 months in the group of patients treated with cisplatin in the combination with pemetrexed and who also received supplementation with folate and vitamin B. Vitamin supplementation was given to most patients in the trial and pemetrexed related side effects were significantly less in patients receiving pemetrexed when they also received daily oral folate 500mcg and intramuscular vitamin B 1000mcg every 9 weeks compared with patients receiving pemetrexed without vitamin supplementation. The objective response rate increased from 20% in the cisplatin group to 46% in the combination pemetrexed group. Some side effects such as nausea and vomiting, stomatitis, and diarrhoea were more common in the combination pemetrexed group but only affected a minority of patients and overall the combination of pemetrexed and cisplatin was well tolerated when patients received vitamin supplementation; both quality of life and lung function tests improved in the combination pemetrexed group. In February 2004, the United States Food and Drug Administration approved pemetrexed for treatment of malignant pleural mesothelioma. However, there are still unanswered questions about the optimal use of chemotherapy, including when to start treatment, and the optimal number of cycles to give. Cisplatin and pemetrexed together give patients a median survival of 12.1 months.

Cisplatin in combination with raltitrexed has shown an improvement in survival similar to that reported for pemetrexed in combination with cisplatin, but raltitrexed is no longer commercially available for this indication. For patients unable to tolerate pemetrexed, cisplatin in combination with gemcitabine or vinorelbine is an alternative, or vinorelbine on its own, although a survival benefit has not been shown for these drugs. For patients in whom cisplatin cannot be used, carboplatin can be substituted but non-randomised data have shown lower response rates and high rates of haematological toxicity for carboplatin-based combinations, albeit with similar survival figures to patients receiving cisplatin.

In January 2009, the United States FDA approved using conventional therapies such as surgery in combination with radiation and or chemotherapy on stage I or II Mesothelioma after research conducted by a nationwide study by Duke University concluded an almost 50 point increase in remission rates.

In pericardial mesothelioma, chemotherapy - typically adriamycin and/or cisplatin - is primarily used to shrink the tumor and is not curative.

Radiotherapy is commonly used to treat Merkel-cell cancers. The radiotherapy fields used are usually very large so as to cover sufficient areas of skin. This is necessary because of MCC's aggressive local and regional metastatic behavior.

Adjuvant radiotherapy has been shown to be effective in reducing the rates of recurrence and in increasing the survival of patients with MCC. Patients who present with no distant metastases and a negative sentinel lymph node biopsy have a very good prognosis when treated with both surgery and radiotherapy (approximately 90% survival rate at five years).

Metastatic MCC may respond to treatment with chemotherapy and/or radiation, but current multimodal therapies are usually not curative. Intensive treatment can be effective in shrinking the tumor and improving operability when tumors are too large to be removed or located in a place where removal would be difficult or dangerous, or in palliation of signs and symptoms caused by metastatic tumors.

a) Surgical resection is mainstay of treatment, whenever possible. If tumor is completely removed, post-operative radiation therapy is typically not needed since acinic cell is considered a low-grade histology. Post-operative radiation therapy for acinic cell carcinoma is used if: 1) margins are positive, 2) incomplete resection, 3) tumor invades beyond gland, 4) positive lymph nodes.

b) Neutron beam radiation

c) Conventional radiation

d) Chemotherapy

The chemotherapy regimen depends on the tumor type. Small-cell lung carcinoma (SCLC), even relatively early stage disease, is treated primarily with chemotherapy and radiation. In SCLC, cisplatin and etoposide are most commonly used. Combinations with carboplatin, gemcitabine, paclitaxel, vinorelbine, topotecan, and irinotecan are also used. In advanced non-small cell lung carcinoma (NSCLC), chemotherapy improves survival and is used as first-line treatment, provided the person is well enough for the treatment. Typically, two drugs are used, of which one is often platinum-based (either cisplatin or carboplatin). Other commonly used drugs are gemcitabine, paclitaxel, docetaxel, pemetrexed, etoposide or vinorelbine. Platinum-based drugs and combinations that include platinum therapy may lead to a higher risk of serious adverse effects in people over 70 years old.

Adjuvant chemotherapy refers to the use of chemotherapy after apparently curative surgery to improve the outcome. In NSCLC, samples are taken of nearby lymph nodes during surgery to assist staging. If stage II or III disease is confirmed, adjuvant chemotherapy (including or not including postoperative radiotherapy) improves survival by 4% at five years. The combination of vinorelbine and cisplatin is more effective than older regimens. Adjuvant chemotherapy for people with stage IB cancer is controversial, as clinical trials have not clearly demonstrated a survival benefit. Chemotherapy before surgery in NSCLC that can be removed surgically may improve outcomes.

Chemotherapy may be combined with palliative care in the treatment of the NSCLC. In advanced cases, appropriate chemotherapy improves average survival over supportive care alone, as well as improving quality of life. With adequate physical fitness maintaining chemotherapy during lung cancer palliation offers 1.5 to 3 months of prolongation of survival, symptomatic relief, and an improvement in quality of life, with better results seen with modern agents. The NSCLC Meta-Analyses Collaborative Group recommends if the recipient wants and can tolerate treatment, then chemotherapy should be considered in advanced NSCLC.

For treatment purposes, MCACL has been traditionally considered a non-small cell lung carcinoma (NSCLC). Complete radical surgical resection is the treatment of choice.

There is virtually no data regarding new molecular targets or targeted therapy in the literature to date. Iwasaki and co-workers failed to find mutations of the epidermal growth factor receptor (EGFR) or the cellular Kirsten rat sarcoma virus oncogene "K-ras" in one reported case.

The U.S. Food and Drug Administration granted in March 2017 an accelerated approval to the checkpoint-inhibitor avelumab for the treatment of adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (MCC). This is the first FDA-approved treatment for metastatic MCC. Avelumab targets the PD-1/PD-L1 pathway (proteins found on the body’s immune cells and some cancer cells). By blocking these interactions, avelumab may help the body’s immune system attack cancer cells.

Sirolimus is an mTOR inhibitor that stabilizes lung function and improves some measures of life in LAM patients. It is approved by the FDA for use in LAM, based on the results of the Multicenter International LAM Efficacy and Safety of Sirolimus (MILES) Trial. MILES data supports the use of sirolimus in patients who have abnormal lung function (i.e. FEV1<70% predicted). Whether the benefits of treatment outweigh the risks for asymptomatic LAM patients with normal lung function is not clear, but some physicians consider treatment for declining patients who are approaching the abnormal range for FEV1. Sirolimus also appears to be effective for the treatment chylous effusions and lymphangioleiomyomatosis. The benefits of sirolimus only persist while treatment continues. The safety of long term therapy has not been studied.

Potential side effects from mTOR inhibitors include swelling in the ankles, acne, oral ulcers, dyspepsia, diarrhea, elevation of cholesterol and triglycerides, hypertension and headache. Sirolimus pneumonitis and latent malignancy are more serious concerns, but occur infrequently. Sirolimus inhibits wound healing. It is important to stop therapy with the drug for 1–2 weeks before and after elective procedures that require optimal wound healing. Precautions must be taken to avoid prolonged sun exposure due to increased skin cancer risk.

Treatment with another mTOR inhibitor, everolimus, was reported in a small, open-label trial to be associated with improvement in FEV1 and six-minute walk distance. Serum levels of VEGF-D and collagen IV were reduced by treatment. Adverse events were generally consistent with those known to be associated with mTOR inhibitors, although some were serious and included peripheral edema, pneumonia, cardiac failure and "Pneumocystis jirovecii" infection. Escalating doses of everolimus were used, up to 10 mg per day; higher than what is typically used clinically for LAM.

Serum VEGF-D concentration is useful, predictive and prognostic biomarker. Higher baseline VEGF-D levels predicts more rapid disease progression and a more robust treatment response.

Hormonal approaches to treatment have never been tested in proper trials. In the absence of proven benefit, therapy with progesterone, GnRh agonists (e.g., Lupron, goserelin) and tamoxifen are not routinely recommended. Doxycycline had no effect on the rate of lung function decline in a double blind trial.

Sirolimus is often effective as first-line management for chylothorax. If chylous leakage or accumulations persist despite treatment, imaging with heavy T2 weighted MRI, MRI lymphangiography or thoracic duct lymphangiography can be considered. Pleural fusion procedures can be considered in refractory cases.

Treatment regimens involving immunotherapy have yielded variable results. For example, intrapleural inoculation of Bacillus Calmette-Guérin (BCG) in an attempt to boost the immune response, was found to be of no benefit to the patient (while it may benefit patients with bladder cancer). Mesothelioma cells proved susceptible to in vitro lysis by LAK cells following activation by interleukin-2 (IL-2), but patients undergoing this particular therapy experienced major side effects. Indeed, this trial was suspended in view of the unacceptably high levels of IL-2 toxicity and the severity of side effects such as fever and cachexia. Nonetheless, other trials involving interferon alpha have proved more encouraging with 20% of patients experiencing a greater than 50% reduction in tumor mass combined with minimal side effects.

When BAC recurs after surgery, the recurrences are local in about three-quarters of cases, a rate higher than other forms of NSCLC, which tends to recur distantly.

Because of its rarity, there have been no randomized clinical trials of treatment of GCCL, and all information available derives from small retrospective institutional series or multicenter metadata.

Three membrane associated tyrosine kinase receptors are recurrently involved in rearrangements in adenocarcinomas: ALK, ROS1, and RET, and more than eighty other translocations have also been reported in adenocarcinomas of the lung.

Targeted therapies: ALK and ROS1 fusions proteins are both sensitive to treatment with the new ALK tyrosine kinase inhibitors (see the Atlas of Genetics and Cytogenetics in Oncology and Haematology,).

Estrogen-containing medications can exacerbate LAM and are contraindicated. Agents that antagonize the effects of estrogen have not been proven to be effective for treatment, but no proper trials have been done. A trial of bronchodilators should be considered in LAM patients, because up to 17% to 25% have bronchodilator-responsive airflow obstruction. Oxygen should be administered to maintain oxyhemoglobin saturations of greater than 90% with rest, exercise and sleep. Bone densitometry should be considered in all patients who are immobilized and/or on antiestrogen therapies, and appropriate therapy instituted for osteoporotic patients. Proper attention should be paid to cardiovascular health following natural or induced menopause. Immunizations for pneumococcus and influenza should be kept up to date. Pulmonary rehabilitation seems to be particularly rewarding in young, motivated patients with obstructive lung disease, but studies to assess this intervention's effect on exercise tolerance, conditioning and quality of life have not been done.
