obsolete malignant neoplasm of corpus uteri, except isthmus

Based on the provided context, I can provide information about a rare type of cancer that affects the corpus uteri.

Carcinosarcoma of the Corpus Uteri

Carcinosarcoma is a rare and aggressive form of cancer that arises from the corpus uteri. It is a malignant mixed epithelial and mesenchymal tumor, composed of high-grade carcinomatous and sarcomatous components [3]. The tumor often presents as a large, poorly circumscribed polypoid mass with necrotic areas and hemorrhage [2].

Characteristics

• Carcinosarcoma is a rare type of uterine cancer that forms in muscle or other tissues of the uterus [5].
• It is a high-grade sarcoma that arises from the endometrial stroma or myometrium without a specific type of differentiation [7].
• The lymphatic system of the corpus uteri is formed by three main lymphatic trunks: utero-ovarian (infundibulopelvic), parametrial, and presacral [10].

Types

• Representative examples of cancers arising in the stromal and muscle tissues of the myometrium include endometrial carcinoma, carcinosarcoma, leiomyosarcoma, and adenosarcoma [11].
• Other types of uterine sarcomas that affect the corpus uteri include COL1A1-PDGFB fusion uterine sarcoma, which has invasive borders and is highly cellular [12].

Reporting

• The failure to assign unspecified uterine cancers to corpus uteri indicates that mortality from cancer of the corpus uteri is still underreported [15].
• Efforts should be made to achieve further improvement in reporting specific subsites of cancer of the uterus on death certificates.

Based on the search results, it appears that there are no specific signs and symptoms mentioned for "obsolete" malignant neoplasm of corpus uteri, except isthmus. However, I can provide information on the general signs and symptoms of this condition.

Irregular Vaginal Bleeding The most common presenting sign of endometrial cancer is irregular vaginal bleeding, which generally occurs early in the disease process [1, 2, 3, 4, 5]. This symptom can manifest as abnormal uterine bleeding, including postmenopausal bleeding or intermenstrual bleeding.

Other Abnormal Bleeding In addition to irregular vaginal bleeding, other abnormal bleeding patterns may be associated with endometrial cancer. These include excessive and frequent menstruation with an irregular cycle [13], excessive bleeding in the premenopausal period [13], and other abnormal bleeding from the uterus [14].

It's essential to note that these symptoms can also be caused by other conditions, and a definitive diagnosis of endometrial cancer requires further medical evaluation.

People with malignant neoplasms usually have varying symptoms depending on where the tumor is located.

Diagnostic Tests for Obsolete Malignant Neoplasm of Corpus Uteri

The diagnostic tests for an obsolete malignant neoplasm of corpus uteri may vary depending on the stage and severity of the condition. However, based on the available information, here are some common diagnostic tests that may be used:

• Blood tests: Blood chemistry tests, including renal and liver function tests, and blood count, may be performed to assess the overall health of the patient and identify any potential complications.
• Imaging tests: Transvaginal ultrasound may be used to provide a detailed view of the uterus and detect any abnormalities in the endometrium or myometrium. A chest X-ray may also be performed to rule out any metastasis to the lungs.
• Biopsy: A biopsy of the affected area may be performed to confirm the diagnosis and assess the extent of the disease.

It's worth noting that the term "obsolete malignant neoplasm of corpus uteri" is not a commonly used medical term, and it's possible that this condition has been reclassified or renamed in modern medical literature. However, based on the available information, the following sources suggest that the diagnostic tests mentioned above may be relevant:

• [12] mentions that blood tests, including CA-125 assay, may be performed to diagnose uterine cancer.
• [14] states that full biochemistry (renal and liver function tests), and blood count also represent routine tests in the diagnosis of corpus uterine cancers.
• [15] mentions that staging of endometrial cancer is based on non-aggressive versus aggressive histology, extent of spread, including invasion depth, extension to surrounding structures, and extrauterine or lymph node metastases.

Please note that these sources are not specifically addressing "obsolete malignant neoplasm of corpus uteri", but rather provide general information on the diagnosis and staging of endometrial cancer.

Based on the provided context, it appears that you are looking for information on the drug treatment of endometrial cancer (malignant neoplasm of the corpus uteri), excluding the isthmus.

Chemotherapy and Hormone Therapy

For women with advanced endometrial cancer or whose cancer has spread beyond the uterus to other parts of the body, chemotherapy and hormone therapy may be used as a treatment option [1]. Chemotherapy involves using anticancer drugs to destroy cancer cells, while hormone therapy aims to block the production or action of hormones that can fuel the growth of cancer cells [7].

Targeted Therapy

In addition to chemotherapy and hormone therapy, targeted therapy is also an option for some women with endometrial cancer. Targeted therapies work by targeting specific molecules involved in the growth and spread of cancer cells. For example, lenvatinib (Lenvima) can be used along with immunotherapy drug Keytruda to treat advanced endometrial cancer [8].

Immunotherapy

Immunotherapy is another type of treatment that uses the body's immune system to fight cancer. Dostarlimab-gxly, a monoclonal antibody, has been approved by the FDA for the treatment of endometrial cancer [11].

Other Medications

Other medications such as progestins (e.g., megestrol acetate) may also be used in the treatment of endometrial cancer. These medications can help lower estrogen levels or block the action of estrogen, which can slow down the growth of tumor cells that rely on estrogen for growth [5].

Based on the search results, I was able to find relevant information on the differential diagnosis of malignant neoplasm of corpus uteri, excluding isthmus.

The differential diagnosis for this condition includes:

• Endometrial hyperplasia: This is a non-cancerous condition where the lining of the uterus grows too thick. It can be a precursor to endometrial cancer (N85.00 - N85.02) [1].
• Excessive and frequent menstruation with irregular cycle (N92.1): While not directly related, this condition can sometimes be associated with endometrial hyperplasia or other abnormal uterine conditions.
• Other abnormal bleeding from the uterus: This includes various conditions such as metrorrhagia, menorrhagia, and postmenopausal bleeding, which may require differential diagnosis (N92.4 - N93.8) [1].
• Extension of a primary endocervical adenocarcinoma into the uterine isthmus: This is another condition that can be considered in the differential diagnosis, especially if there are symptoms or findings suggestive of cervical involvement.
• Immunohistochemistry may be helpful in making this distinction [4].

It's also worth noting that the classification and staging of endometrial cancer have evolved over time. The traditional division into Type 1 (endometrioid and mucinous carcinoma) and Type 2 (serous, clear cell, etc.) is still used, but more recent studies have proposed additional subtypes [3].
