Treatment depends on the cause. In cases where malignancy is ruled out, hormone supplementation or the therapeutic use of hormonal contraception is usually recommended to induce bleeding on a regular schedule. Selective progesterone receptor modulators (SPRMs) are sometimes used to stop uterine bleeding.

Menometrorrhagia is a condition in which prolonged or excessive uterine bleeding occurs irregularly and more frequently than normal. It is thus a combination of metrorrhagia and menorrhagia.

Dysmenorrhea (or dysmenorrhoea), cramps or painful menstruation, involves menstrual periods that are accompanied by either sharp, intermittent pain or dull, aching pain, usually in the pelvis or lower abdomen.

Abnormal uterine bleeding is a general category that includes any bleeding from menstrual or nonmenstrual causes. Hypomenorrhea is abnormally light menstrual periods. Menorrhagia (meno = month, rrhagia = excessive flow/discharge) is an abnormally heavy and prolonged menstrual period. Metrorrhagia is bleeding at irregular times, especially outside the expected intervals of the menstrual cycle. If there is excessive menstrual and uterine bleeding other than that caused by menstruation, menometrorrhagia (meno = prolonged, metro = uterine, rrhagia = excessive flow/discharge) may be diagnosed. Causes may be due to abnormal blood clotting, disruption of normal hormonal regulation of periods or disorders of the endometrial lining of the uterus. Depending upon the cause, it may be associated with abnormally painful periods.

Hormone therapies are a topic of current research in ovarian cancer, particularly, the value of certain medications used to treat breast cancer. These include tamoxifen, letrozole, and anastrozole. Preliminary studies have showed a benefit for tamoxifen in a small number of people with advanced ovarian cancer. Letrozole may help to slow or stop growth of estrogen receptor positive ovarian cancer. Anastrozole is being investigated in postmenopausal people with estrogen receptor-positive cancer.

Research into mitigating side effects of ovarian cancer treatment is also ongoing. Radiation fibrosis, the formation of scar tissue in an area treated with radiation, may be relieved with hyperbaric oxygen therapy, but research has not been completed in this area. Treatment of ovarian cancer may also cause people to experience psychiatric difficulties, including depression. Research is ongoing to determine how counseling and psychotherapy can help people who have ovarian cancer during treatment.

Palliative care focuses on relieving symptoms and increasing or maintaining quality of life. This type of treatment's purpose is not to cure the cancer but to make the woman more comfortable while living with cancer that can not be cured. It has been recommended as part of the treatment plan for any person with advanced ovarian cancer or patients with significant symptoms. In platinum-refractory and platinum-resistant cases, other palliative chemotherapy is the main treatment.

Palliative care can entail treatment of symptoms and complications of the cancer, including pain, nausea, constipation, ascites, bowel obstruction, edema, pleural effusion, and mucositis. Especially if the cancer advances and becomes incurable, treatment of symptoms becomes one of the main goals of therapy. Palliative care can also entail helping with decision-making such as if or when hospice care is appropriate, and the preferred place for the patient at end of life care.

Bowel obstruction can be treated with palliative surgery (colostomy, ileostomy, or internal bypass) or medicine, but surgery has been shown to increase survival time. Palliative surgery may result in short bowel syndrome, enterocutaneous fistula, or re-obstruction; or may not be possible due to the extent of obstruction. Other treatments of complications can include total parenteral nutrition, a low-residue diet, palliative gastrostomy, and adequate pain control. Bowel obstruction can also be treated with octreotide when palliative surgery is not an option. Cancer can also block the ureters, which can be relieved by a nephrostomy or a ureteric stent. Ascites can be relieved by repeated paracentesis or placement of a drain to increase comfort. Pleural effusions can be treated in a similar manner, with repeated thoracentesis, pleurodesis, or placement of a drain.

Radiation therapy can be used as part of the palliative care of advanced ovarian cancer, since it can help to shrink tumors that are causing symptoms. Palliative radiotherapy typically lasts for only a few treatments, a much shorter course of therapy than non-palliative radiotherapy. It is also used for palliation of chemotherapy-resistant germ cell tumors.

Blood relatives of the proband case should be evaluated for the presence of hypodysfibrinogenemia. Individuals with the disorder need to be advised on its inheritance, complications, and preventative measures that can be taken to avoid bleeding and/or thrombosis. Since >80% of individuals may develop bleeding or thrombosis complications of the disorder, asymptomatic individuals diagnosed with hydposyfibrinogenemia are best handled at a specialized center in order to benefit from multidisciplinary management.

Measures to prevent and/or treat complications of hypodysfibrinogenemia should be tailored to the personal and family history of the individual by a specialized center. Individuals with a personal or family history of bleeding are considered to be of low risk of bleeding when their functional fibrinogen levels are >1 gram/liter for major surgery, >0.5 gram/liter for minor surgery, >0.5 to 1-2 gram/liter for spontaneous bleeding (depending on its severity), >0.5 to > 1 gram/liter for the first two trimesters of pregnancy, and >1 to <2 gram/liter for the last trimester of pregnancy and postpartum period. Functional fibrinogen below these levels should be treated preferably with fibrinogen concentrate or if not available, fibrinogen-rich cryoprecipitate or plasma to attain low risk levels of functional fibrinogen. Antifibrinolytic drugs such as tranexamic acid or (ε-aminocaproic acid) may be considered as an alternative preventative or therapeutic treatments in cases of minor surgery, dental extractions, mucosal bleeding, or other episodes of mild bleeding. In individuals with a personal or family history of thrombosis, should be considered for long-term anticoagulation drugs such as low molecular weight heparin, coumadin, or rivaroxaban.

Hypodysfibrinogenemia, also termed congenital hypodysfibrinogenemia, is a rare hereditary fibrinogen disorder cause by mutations in one or more of the genes that encode a factor critical for blood clotting, fibrinogen. These mutations result in the production and circulation at reduced levels of fibrinogen at least some of which is dysfunctional. Hypodysfibrinogenemia exhibits reduced penetrance, i.e. only some family members with the mutated gene develop symptoms.

The disorder is similar to a form of dysfibrinogenemia termed congenital dysfibrinogenemia. However, congenital dysfibrinogenemia differs form hypodysfibrinogenemia in four ways. Congenital dysfibrinogenemia involves: the circulation at normal levels of fibrinogen at least some of which is dysfunctional; a different set of causative gene mutations; a somewhat different mix of clinical symptoms; and a much lower rate of penetrance.

Hypodysfibrinogenemia causes episodes of pathological bleeding and thrombosis due not only to low levels of circulating fibrinogen but also to the dysfunction of a portion of the circulating fibrinogen. The disorder can lead to very significant bleeding during even minor surgical procedures and women afflicted with the disorderoften suffer significant bleeding during and after giving child birth, higher rates of miscarriages, and menorrhagia, i.e. abnormally heavy bleeding during the menstrual period.

Granulosa cell tumours (or granulosa-theca cell tumours or folliculoma) are tumours that arise from granulosa cells. These tumours are part of the sex cord-gonadal stromal tumour or non-epithelial group of tumours. Although granulosa cells normally occur only in the ovary, granulosa cell tumours occur in both ovaries and testicles (see Ovarian cancer and Testicular cancer). These tumours should be considered malignant and treated in the same way as other malignant tumours of ovary. The ovarian disease has two forms, juvenile and adult, both characterized by indolent growth, and therefore has high recovery rates.

The staging system for these tumours is the same as for epithelial tumours and most present as stage I. The peak age at which they occur is 50–55 years, but they may occur at any age.

Juvenile granulosa cell tumour is a similar but distinct rare tumour. It too occurs in both the ovary and testis. In the testis it is extremely rare, and has not been reported to be malignant. Although this tumour usually occurs in children (hence its name), it has been reported in adults.

Estrogens are produced by "functioning" tumours, and the clinical presentation depends on the patient's age and sex.

- Female

- If the patient is postmenopausal, she usually presents with abnormal uterine bleeding, and in some cases hemoperitoneum.

- If the patient is of reproductive age, she would present with menometrorrhagia. However, in some cases she may stop ovulating altogether.

- If the patient has not undergone puberty, early onset of puberty may be seen.

- these tumors tend to have late recurrencies ( even after 30 years )

Treatment options include:

1. Therapies to eliminate the underlying cancer, such as chemotherapy, radiation and surgery.

2. Therapies to reduce or slow neurological degeneration. In this scenario, rapid diagnosis and treatment are critical for the patient to have the best chance of recovery. Since these disorders are relatively rare, few doctors have seen or treated paraneoplastic neurological disorders (PNDs). Therefore, PND patients should consult with a specialist with experience in diagnosing and treating paraneoplastic neurological disorders.

A specific prognosis for those afflicted with paraneoplastic syndromes links to each unique case presented. Thus, prognosis for paraneoplastic syndromes may vary greatly. For example, paraneoplastic pemphigus often included infection as a major cause of death. Paraneoplastic pemphigus is one of the three major subtypes that affects IgG autoantibodies that are characteristically raised against desmoglein 1 and desmoglein 3 (which are cell-cell adhesion molecules found in desmosomes). Underlying cancer or irreversible system impairment, seen in acute heart failure or kidney failure, may result in death as well.

Prostate cancer is the second most common urological malignancy to be associated with paraneoplastic syndromes after renal cell carcinoma. Paraneoplastic syndromes of this nature tend to occur in the setting of late stage and aggressive tumors with poor overall outcomes (endocrine manifestations, neurological entities, dermatological conditions, and other syndromes). A vast majority of prostate cancer cases (over 70%) document paraneoplastic syndrome as a major clinical manifestation of prostate cancer; and interestingly (under 20%), the syndrome as an initial sign of disease progression to the castrate-resistant state. Urologist researchers identify serum markers that are associated with the syndrome in order to specific what type of therapies may work most effectively.

Paraneoplastic neurological syndromes may be related immune checkpoint inhibitors (ICIs), one of the underlying causes in inflammatory central nervous system diseases (CNS). The central idea around such research pinpoints treatment strategies to combat cancer related outcomes in the clinical arena, specifically ICIs. Research suggests that patients who are treated with ICIs are more susceptible to CNS disease (since the mechanism of ICIs induces adverse effects on the CNS due to augmented immune responses and neurotoxicity). The purpose of this exploration was to shed light on immunotherapies and distinguishing between neurotoxicity and brain metastasis in the early stages of treatment. In other research, scientists have found that paraneoplastic peripheral nerve disorders (autoantibodies linked to multifocal motor neuropathy) may provide important clinical manifestations. This is especially important for patients who experience inflammatory neuropathies since solid tumors are often associated with peripheral nerve disorders. CV2 autoantibodies, which target dihydropyriminase-related protein 5 (DRP5, or CRMP5) are also associated with a variety of paraneoplastic neurological syndromes, including sensorimotor polyneuropathies. Interestingly, patients undergoing immune therapies or tumor removal respond very well to antibodies that target CASPR2 (to treat nerve hyperexcitability and neuromyotonia).

In the case of paraneoplastic Cushing's syndrome arising from a small cel carcinoma of the endometrium, paraneoplastic syndrome has been seen to interfere with standard treatments and lead to unexpected complications and clinical course. The purpose of this clinical case demonstrates the aggressive nature of the neuroendocrine small cell carcinoma with rapid invasion and extra-uterine spread. The researchers raise recognition for timely recognition of paraneoplastic syndrome, which in this particular case use a combinatorial therapy of etoposide and cisplatin chemotherapy to save the 32-year old female patient's life (presented with persistent migraine-like headache, palpitations, progressive nausea and vomiting, photo- and sonobia, menometrorrhagia and concomitant general fatigue).
