obsolete secondary malignant neoplasm of large intestine and rectum

Obsolete Terms for Secondary Malignant Neoplasm of Large Intestine and Rectum

The terms "secondary malignant neoplasm of colon and/or rectum" and "malignant tumor of large intestine (disorder)" are considered obsolete. These terms were previously used to describe cancer that has spread from another site to the colon or rectum.

• The term "secondary malignant neoplasm of colon and/or rectum" is no longer preferred, but it was once used as a designated name for this condition.
• The term "malignant tumor of large intestine (disorder)" is also considered obsolete, with a code of 94365007 assigned to it.

Current Terminology

The current terminology for cancer that has spread from another site to the colon or rectum is more specific and accurate. This condition is now referred to as secondary malignant neoplasm of large intestine and rectum, with a corresponding ICD-10 code of C78.5.

• The term "C78.5" is a valid billable code for this condition, indicating that it is a specific diagnosis that can be used for reimbursement purposes.
• This code is found in the 2024 version of the ICD-10 Clinical Modification and can be used in all HIPAA-covered transactions from October 1, 2023 to September 30, 2024.

Note: The information provided above is based on the search results and context provided, which includes obsolete terms that are no longer used in medical practice.

Based on the provided context, here are the signs and symptoms of obsolete secondary malignant neoplasm of large intestine and rectum:

• A change in bowel habits, such as diarrhea, constipation or a more-frequent need to pass stool [11]
• Bleeding in the rectum [11]

It's worth noting that these symptoms may also be associated with other conditions, and a definitive diagnosis can only be made through medical evaluation and testing.

In addition, it's mentioned that malignant cells form in the lining of the intestine or rectum, which is a characteristic of colorectal cancer [15]. However, this information is more related to primary malignant neoplasm rather than secondary one.

It's also stated that second malignant neoplasms (SMNs) now represent approximately 16% (or one in six) cancers reported to the National Cancer Institute's (NCI's) Surveillance, Epidemiology, and End Results (SEER) Program [13]. However, this information is more related to the prevalence of SMNs rather than their specific symptoms.

Based on the provided context, it appears that there are various diagnostic tests used to detect secondary malignant neoplasms of the large intestine and rectum.

• Enteroclysis is a test for small intestine cancer, but it may also provide detailed pictures of the large intestine (Context 4). However, its relevance to diagnosing secondary malignant neoplasms of the large intestine and rectum is unclear.
• Barium enema involves inserting barium into the rectum, filling the colon, and taking X-rays. This test can help detect polyps and other abnormalities in the large intestine (Context 4). However, its effectiveness in diagnosing secondary malignant neoplasms of the large intestine and rectum is not specified.
• Endoscopic ultrasound (also referred to as endorectal ultrasound) is used for staging rectal cancer. It involves using a thin, flexible tube with a camera to visualize the rectum and colon (Context 12). This test may be useful in diagnosing secondary malignant neoplasms of the large intestine and rectum.
• Fecal occult blood tests are widely used to screen the colon for cancer. They can also help investigate symptoms by detecting bleeding in the gastrointestinal tract (Context 15).

It's essential to note that these diagnostic tests may not be specifically designed for secondary malignant neoplasms of the large intestine and rectum. However, they may still provide valuable information for diagnosis.

Based on the provided context, it appears that there are various treatment options available for secondary malignant neoplasms of the large intestine and rectum.

• For stage IV rectal cancer, chemotherapy drugs such as Fluorouracil (5-FU) [6] and Bevacizumab [7] are commonly used in combination with other treatments.
• Cetuximab and panitumumab are available on the NHS for advanced bowel cancer, which can include secondary malignant neoplasms of the large intestine and rectum [4].
• Treatment options for colon cancer, including surgery, chemotherapy, radiation therapy, and targeted therapy, may also be applicable to secondary malignant neoplasms of the large intestine and rectum [5].

It's worth noting that treatment options can vary depending on the specific characteristics of the cancer, such as its stage and location. It's always best to consult with a healthcare professional for personalized advice.

The differential diagnosis for secondary malignant neoplasm of large intestine and rectum (C78.6) involves considering various conditions that may present with similar symptoms or characteristics.

• Gastrointestinal Stromal Tumor (GIST): This is a type of tumor that arises from the interstitial cells of Cajal in the intestinal wall [12]. GISTs can be either benign or malignant and are the most common mesenchymal tumors of the GI tract, with the rectum being one of the most affected areas.
• Smooth Muscle Tumors: These include a range of conditions such as leiomyomas, leiomyosarcomas, and others that can arise in the intestinal wall [8].
• Colorectal Cancer (CRC): This is a primary malignant neoplasm of the large intestine and rectum, which can also be considered in the differential diagnosis.
• Peritoneal Metastasis: Patients with peritoneal metastasis from colorectal cancer represent a distinct subset with regional disease rather than systemic disease [4].

When considering the differential diagnosis for secondary malignant neoplasm of large intestine and rectum (C78.6), it is essential to take into account the patient's medical history, symptoms, and diagnostic findings.
