From January 1981 to December 1987, 59 major upper abdominal operations were performed on 57 patients aged 80 to 90 years at Memorial Sloan-Kettering Cancer Center. Procedures for primary adenocarcinoma of the stomach, distal esophagus, pancreas, or hepatobiliary system were performed with curative intent or for palliation in 34 of 59 patients (58%) and bypass with limited or no resection in 13 of 59 patients (22%) patients. Emergency operations were performed in six (10%) patients for gastric bleeding, perforation, or outlet obstruction. Six (10%) patients underwent laparotomy for benign biliary obstruction (1), splenectomy for secondary thrombocytopenia (2), or gastrectomy for sarcoma (2) or lymphoma (1). Hospital mortality was 15% overall and 9% for major resections, 15% for bypass, and 67% for emergency procedures. Major complications occurred in 10 (20%) elective procedures. Mortality was associated with respiratory or cardiac failure while complications most commonly included arrhythmias and wound infection. Mean postoperative hospitalization was 18 days overall and 45 patients (76%) were discharged home. Median survival following major resection was 17.5 months but less than 2 months after bypass procedures. A protocol of pre-operative evaluation, intra-operative hemodynamic monitoring and postoperative intensive care has been formalized for use in elderly or poor-risk patients.

Synchronous double malignancies of gastric carcinoma (GC) and malignant lymphoma (ML) are rare and very difficult to treat. We report a case of synchronous GC and nodal ML, regarding which clinical and pathological features and treatment are discussed. A 68-year-old woman with a history of inguinal hernia was admitted for abdominal pain and high fever and subsequently underwent herniorrhaphy, but the fever remained. Computerized tomography showed a stomach mass and multiple enlarged lymph nodes in the abdominal cavity and inguinal regions. Gastric adenocarcinoma coexistent with advanced in situ follicular lymphoma was confirmed by endoscopy, biopsy of inguinal lymph nodes and bone marrow examination. Two chemotherapy regimens, R-CHOP (rituximab, cyclophosphamide, perarubicin, vincristine and prednisone) and systemic therapy (5-fluorouracil and calcium folinate) combined with regional perfusion (oxaliplatin and etoposide) through the left gastric artery were performed at intervals against ML and GC, respectively. Partial remission in both tumors was achieved after 4 courses of treatment, but the patient finally died of heart failure. Scrupulous biopsy of non-draining lymph nodes in patients with gastrointestinal carcinomas is supposed to improve the diagnostic rate of simultaneous nodal ML. The interval chemotherapy strategy with two independent regimens is beneficial for such patients, especially for those unable to tolerate major surgery.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare complication occurring during tumor dissemination that can lead to severe, commonly unrecognized pulmonary hypertension, right-sided heart failure, and sudden death. Histologically, it is characterized by tumor microthrombi within small arteries and arterioles and associated fibrocellular and fibromuscular intimal proliferation. Gastric adenocarcinoma is the most common tumor type with this association. Of gynecologic malignancies, a single case of ovarian clear cell carcinoma has been linked to PTTM. We report 2 patients who underwent surgery with a preoperative diagnosis of pelvic mass. After surgery, the patients had unexplained progressive respiratory failure that led to their death. Autopsy revealed typical features of PTTM with tumor lymphangitic spread and microscopic tumor emboli within the lung arteries. In both cases, the primary tumor was an ovarian serous neoplasm of low malignant potential with widespread dissemination, 1 with microinvasion and progression to low-grade serous carcinoma. In this last case, mutational analysis for KRAS and BRAF genes was performed to confirm the association between the ovarian and the extraovarian tumor and rule out other primary tumors more commonly associated with this disease. PTTM is a distinct pathologic entity with very few cases reported in the literature, especially involving ovarian tumors. We report 2 cases of low-grade ovarian serous neoplasm, not previously reported with this association.

A 33-year-old female collapsed and died suddenly after presenting with acute dyspnea and increasing cough over the preceding several months. Autopsy revealed poorly differentiated linitis plastica adenocarcinoma of the stomach. Microscopic examination of the lungs showed features consistent with pulmonary tumor thrombotic microangiopathy (PTTM). PTTM is a well-described complication in patients with adenocarcinoma. The typical presentation involves acute pulmonary hypertension, right-sided heart failure, and sudden death, often before the adenocarcinoma is discovered. The pathophysiology of PTTM remains elusive; it has been suggested that carcinoma cells may produce substances that influence pulmonary vasculature. Our patient had classic clinical and histologic features of PTTM in addition to prominent extravascular compression by intralymphatic tumor cells. These features undoubtedly caused her precipitous decline and lethal pulmonary hypertension, induced by underlying adenocarcinoma. This case demonstrates that sudden death can occur from pulmonary hypertension induced by metastatic carcinoma with remarkably little prior symptomatology.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rapidly progressive and often fatal pulmonary disease induced by tumor emboli within the small pulmonary arteries. PTTM presents clinically as progressive hypoxia and pulmonary hypertension. Most cases of PTTM are caused by an adenocarcinoma of the stomach. We present the first case report of PTTM caused by cervical squamous cell carcinoma. An 82-year-old woman presented with vaginal bleeding and exertional dyspnea. A cervical mass biopsy showed squamous cell carcinoma. Computed tomography revealed ground glass opacity of the bilateral peripheral lung fields. Hypoxia and pulmonary hypertension gradually worsened after admission. Treatment for acute heart failure was started, but was ineffective. She died of respiratory failure 31 days after admission. She was diagnosed at autopsy as having PTTM induced by cervical squamous cell carcinoma. PTTM needs to be considered in any patient with advanced cancer and lung-related issues to rule out metastatic disease, even in the absence of imaging findings.
