Axillary lymph node metastasis in lung cancer

Study objectives Axillary lymph node metastasis (ALNM) from lung cancer is rare. Its prognosis and effective treatments remain unknown. To evaluate clinicopatholgical characteristics of such lung cancer patients, we performed a retrospective study of them, who had ALNM at the time of initial presentation or developed ALNM in their clinical courses. Methods We reviewed the medical records and pathological reports of all patients at our division who had a diagnosis of primary lung cancer from January 1985 through August 2007. Results Ten (0.75%) of 1,340 patients had ALNM. In eight of them, ALNM was detected at the time of initial diagnosis, and two patients developed ALNM in their clinical courses. Lymphatic metastasis to mediastinum was evident in all patients. Supraclavicular and cervical lymph nodes were involved in five and three patients, respectively. One patient had direct chest wall invasion from the lung. Three patients had distant metastases other than axillary or cervical lymph nodes. Four patients received systemic chemotherapy, and another four patients received palliative chest irradiation or supportive care because of their poor performance status. Median survival time of 8 patients who were diagnosed as having ALNMs at initial presentation was 7 months. Conclusions The most likely mechanism for axillary node involvement is intercostal lymphatics via spread from mediastinal lymph node metastasis. Routine palpation of the axillae is recommended if chest wall invasion, mediastinal and/or supraclavicular lymph nodes are found either at initial presentation or at follow-up of patients.

Clinicopathological and radiological evaluation of cervical lymph node metastasis in head and neck malignancies

The cervical lymphadenopathy due to metastasis carry poor prognosis. The status of cervical nodes is of critical interest to surgical, radiation and medical oncologists who manage patients with head and neck cancers. We conducted a prospective randomized study to assess the role of palpation, ultrasound and CT in detection of cervical metastasis in 25 patients presented to us with head and neck malignancy irrespective of cervical nodal status. It was observed that clinical examination was least sensitive (73.33%) when compared with computerized tomography (80%) and ultrasound (93.93%). The computerized tomography was found to be most specific (90%) when compared to clinical examination or ultrasonography (70% each).     

Rectal cancer with jumping metastasis to the obturator lymph node only

In May, 1993, we operated upon a 40-year-old woman with lower rectal cancer with jumping metastasis to a solitary right obturator lymph node only. For the rectal cancer with submucosal invasion, we performed low anterior resection with regional lymph node dissection as far as the second group, based on theGeneral rules for clinical and pathological studies on cancer of colon, rectum and anus, 4th edition, of the Japanese Society for Cancer of the Colon and Rectum, including the obturator lymph nodes. Well differentiated adenocarcinoma and mucinous carcinoma were seen in the submucosal invasive front. The risk of obturator metastasis must be considered during operation for rectal cancer.     

Oncologic significance of para-aortic lymph node and inferior mesenteric lymph node metastasis in sigmoid and rectal adenocarcinoma

Background

Recurrence patterns or survival in colorectal cancer patients might differ according to inferior mesenteric lymph node (IMLN) metastasis. However, few studies have compared para-aortic lymph node (PALN) metastasis and IMLN metastasis. The aim of the current study is to identify survival and recurrence patterns in patients with sigmoid colon and rectal adenocarcinoma with either PALN or IMLN metastasis and to evaluate the prognostic significance of PALN and IMLN metastasis.
