C77.3
Secondary and unspecified malignant neoplasm of axilla and upper limb lymph nodes
Clinical Classification Guidelines
Inclusion Terms
- Secondary and unspecified malignant neoplasm of pectoral lymph nodes
Medical Intelligence & Overview
ICD-10 code C77.3 refers to secondary or unspecified malignant tumors found in the lymph nodes located in the axilla (armpit area) and upper limb, including the pectoral lymph nodes. These lymph nodes are part of the lymphatic system, which helps defend the body against infections and plays a key role in the spread of cancer. When a tumor is described as 'secondary,' it indicates that cancer has spread from its primary site to these lymph nodes. Understanding this diagnosis can help patients grasp the nature of the disease and the importance of treatment and care.
Causes & Symptoms
Clinical Causes: Metastasis from primary cancers located in breasts, lungs, or upper limbs. Spread of cancer cells through lymphatic channels to regional lymph nodes. Advanced stages of cancers that initially originated in other parts of the body.
Key Symptoms: Swelling or enlargement of lymph nodes in the armpit or upper arm. Persistent pain or discomfort near the affected lymph nodes. Changes in skin over the lymph nodes, such as redness or warmth. Possible signs of the primary cancer, like breast lumps or airway issues, depending on the original site. Unexplained weight loss or fatigue in some cases.
Diagnostic & Treatment
Diagnosis Path: Physical examination focusing on swollen lymph nodes. Imaging tests like ultrasound, MRI, or PET scans to visualize affected areas. Biopsy of the lymph node to identify cancer cells and determine the primary source. Laboratory tests, including blood work, to assess overall health and cancer markers. Assessment of the primary tumor site if not previously identified.
Treatment Protocols: Systemic therapies such as chemotherapy to target cancer cells throughout the body. Targeted therapy designed to attack specific molecular features of the cancer. Radiation therapy to shrink or destroy cancerous lymph nodes. Surgical removal of affected lymph nodes or primary tumors, if feasible. Palliative care to manage symptoms and improve quality of life when curative treatment isn't possible.
