The role of radiotherapy for thymic carcinoma.

Objective: The aim of this study is to evaluate retrospectively the role of radiotherapy for thymic carcinoma.

Methods: Between 1973 and 1998, 14 patients with thymic carcinoma were treated at Gunma Prefectural Cancer Center. Two patients who had hematogenous metastasis were excluded from this study, therefore 12 patients were analyzed.

The proportion of consolidation to ground-glass opacity on high resolution CT is a good predictor for distinguishing the population of non-invasive peripheral adenocarcinoma.

Objective: If non-invasive lung carcinomas are distinguishable on computed tomography (CT), limited surgery can be indicated before operation as a radical procedure. The purpose of this study is to define high resolution CT (HRCT) findings that indicate pathologic T1N0M0 tumor without vessel invasion.

Patients And Methods: We reviewed HRCT findings and pathological specimens of 98 consecutive patients underwent lobectomy or pneumonectomy with systematic hilar and mediastinal lymph node dissection from January 1996 to October 1999 for 101 pulmonary peripheral adenocarcinomas smaller than 3cm in diameter on HRCT.

A unique collision of epithelioid hemangioendothelioma and bronchioloalveolar carcinoma in a 54-year-old Japanese woman.

We present a unique collision of epithelioid hemangioendothelioma and bronchioloalveolar carcinoma. A 54-year-old Japanese woman seen for a small nodular shadow on chest X-ray in December 1989 was found in chest computed tomography to have multiple small nodules in bilateral lung fields. At thoracotomy through a median sternotomy, 9 nodules from 0.

A long-term survivor of complete resection for stage IIB adenocarcinoma of the lung and chemoradiotherapy for postoperative metastasis to the abdominal rectus muscle.

We report long-term survival of very rare metastatic involvement and an unusual course of recurrent stage IIB lung adenocarcinoma. Nine months after surgery for stage IIB primary lung adenocarcinoma, a 64-year-old Japanese man was found to have a nodule in the abdominal rectus muscle, diagnosed histologically as carcinoma metastasizing from the lung. Through combined chemotherapy and subsequent radiotherapy, complete response of the metastatic lesion was achieved without serious adverse effects.
