J. Maxwell Chamberlain Memorial Paper. Role of staging in prognosis and management of thymoma.

Eighty-five patients operated on for thymoma from 1972 to 1989 were evaluated, 32 with myasthenia gravis and 53 without. Masaoka staging revealed stage I disease in 45 (53%), stage II in 23 (27%), stage III in 14 (16%), and stage IVa in 3 (4%). There was no operative mortality. Actuarial survival at 10 years was 63.7% for all patients: 78.3% for those in stage I, 74.7% for those in stage II, and 20.8% for those in stage III. There was no recurrence in patients in stage I. Mediastinal recurrence developed in 4 patients in stage II considered to have noninvasive disease by the surgeon. It is recommended that all patients be followed up for a minimum of 10 years and that all patients in stages II and III receive postoperative radiotherapy. The presence of myasthenia gravis is no longer considered as an adverse factor in survival.

Samuel Robinson, pioneer thoracic surgeon (1875-1947).

Sam Robinson was born in Augusta, ME, in 1875. A graduate of Harvard Medical School, and of the Massachusetts General Hospital (MGH), he worked in the laboratory of Walter Cannon. While a junior at MGH he spent four months abroad with Ferdinand Sauerbruch. He returned to Boston and remained there until 1912, performing his first successful lobectomy for bronchiectasis in 1909. He made important contributions to the management of pneumothorax during operation, notably Sam Robinson's box. In 1912 he moved to Clifton Springs, NY. From 1915 to 1917 he was the first Chief of Thoracic Surgery at the Mayo Clinic. Illness, probably bronchiectasis, led him to abandon academic thoracic surgery in 1918 and retire to Santa Barbara, CA, where he practiced general surgery until 1947. He was President of the Association for Thoracic Surgery in 1922. In addition to the use of positive pressure and early resections, his contributions include artificial pneumothorax for tuberculosis and management of acute and chronic empyema. His colorful writings provide a vivid picture of the early days of our specialty.

Pulmonary resection for metastases from gynecologic cancers: Massachusetts General Hospital experience, 1943-1982.

Fifteen patients with pulmonary metastases from gynecologic cancers have been evaluated and treated surgically at the Massachusetts General Hospital from 1943 to 1982. These women have had primary tumors involving the cervix (6), endometrium (3), and ovary (2) as well as uterine sarcomas (2) and choriocarcinomas (2). Two-year Kaplan-Meier survival for this group was 71%; the corresponding survival at 5 years was 36%. No hospital mortality was encountered. Patients with solitary lesions of less than 4 cm diameter appeared to have the most favorable prognosis in the group. A prolonged time to initial recurrence (latent period) of greater than 36 months was associated with improved survival and there was a 60% survival among patients with latent periods of 60 months or more. An aggressive approach to resection of pulmonary metastases in selected patients provides gratifying palliation for the majority of women and long-term cure in a significant minority.

Changing times in surgical management of bronchopulmonary carcinoid tumor.

The bronchopulmonary carcinoid tumor occurs at all levels from trachea to lung periphery. It should be managed by conservatism in airway or lung resection. The long-term survival is excellent: 82% at 10 years in this series of 111 resected patients. The atypical carcinoid tumor (10% of this series) has a more ominous prognosis and requires special surgical attention. Six conceptual changes in the evolution of management of the tumor are presented (the "changing times").

Combined approach to "dumbbell" intrathoracic and intraspinal neurogenic tumors.

The unexpected finding of an extension of a neurogenic tumor from the thorax through the spinal foramen into the neural canal complicates its removal. Serious neurological complications may result from a two-stage approach, whether done first through the thorax or neural canal. Vertebral tomography or computed tomographic scanning reveals enlargement of a spinal foramen in advance of operation. Myelography confirms the probable presence of an intraspinal component. Four patients have been operated on using an approach designed to allow wide posterolateral thoracotomy and concomitant laminectomy for single-stage removal of the entire tumor. In 3 patients the diagnosis was schwannoma and in 1, neurofibroma. All had good results.
