RESUMO
OBJECTIVES: This case report evaluates the feasibility and efficacy of intraperitoneal (IP) trastuzumab administration in gastric cancer (GC) patients with peritoneal carcinomatoses. METHODS: Peritoneal metastasis is a common sign of advanced tumor stage, tumor progression or disease recurrence in patients with GC. Recently, the role of HER2 overexpression in GC, occurring in about 20% of cases, is correlated with a worse prognosis. We report the case of 61-years old female, admitted to our Hospital after curative surgery for GC with over-expression of HER2. Seven months after the start of first line chemotherapy treatment a pleuro-peritoneal disease progression occurred, documented by cytological exam; according to HER2 status, we decided to treat the patient with IP trastuzumab administration. RESULTS: Between September and October 2012, the patient (ECOG performance status was 0), underwent to 6 cycles of IP trastuzumab. Trastuzumab was administered weekly at a dose of 150 mg for each cycle after paracentesis. The safety was good, no local complications (e.g. abdominal pain, peritonitis) occurred. The clinical revaluation evidenced a stable peritoneal disease. CONCLUSIONS: To our knowledge this is the first report on Trastuzumab use to treat IP metastases from GC, with acceptable toxicity and local disease control.

BACKGROUND: Effort-induced myocardial ischemia (EMI) has been seldom described. Aims of our study were (A) to evaluate the prevalence of EMI during long-lasting 5-FU infusion; (B) to identify possible risk factors of EMI during 5-FU infusion. PATIENTS AND METHODS: For the purpose (A), we prospectively evaluated a group of patients undergoing in-hospital continuous infusion (c.i.) of 5-FU. Patients with rest ischemia were excluded. Among 358 consecutive patients, 21 (5.9%) had rest ischemia; 109 could not perform a stress test. The remaining 228 patients underwent a treadmill stress test (TST) after >46 h of 5-FU infusion. For the purpose (B), we compared the characteristics of patients with EMI (including 3 previously described in a 2001 paper) with those without EMI. RESULTS: Among 228 patients, 16 (6.9%) had EMI. These 16 had a second TST after stopping 5-FU: in 14, it was negative, 2 patients with coronary artery disease had milder ischemia. The whole group of 231 (including 3 described in a previous paper) patients undergoing TST included 148 males and 83 females, with mean age of 57.5. Cardiovascular risk factors were present in 178 of them. Eight patients had ischemic heart disease. Among 19 patients with EMI, 7 had angina, 12 silent ischemia. ST segment at ECG was elevated in 10 patients, depressed in 9. Comparing the group with toxicity and the one without, the only significant difference was the complaint of atypical symptoms at rest before the TST. No difference was observed as regards: chemotherapy schedule (chronic c.i. in 49, 5 days in 178, FOLFOX type in 12), coronary risk factors or heart disease. CONCLUSIONS: EMI is as frequent as rest ischemia during 5-FU infusion. Patients undergoing 5-FU continuous infusions should be adviced to avoid unusual efforts, to refer any cardiac symptom, and should be investigated for EMI.

We describe a rare case of small-cell lung carcinoma invading the left atrium through a pulmonary vein. Echocardiography was particularly useful in this case in assessing the intracavitary extension of the tumor and the outcome of therapy. Echocardiography is a low-cost, easy imaging tool, complementary to radiological techniques and useful in evaluating thoracic tumors involving the cardiovascular structures.

We examined the acute hemodynamic response to Captopril, an oral converting enzyme inhibitor, in 13 patients with chronic congestive heart failure (CHF) refractory to conventional therapy, including other vasodilators. Captopril was administered in four increasing doses of 25, 50, 100 and 150 mg. The cardiac index (Cl) increased significantly (average +22%) in patients with high plasma renin activity (PRA). Pulmonary artery diastolic pressure (PADP) considerably decreased in all patients. A moderate decrease in systemic arterial pressure (SAP) was also observed. The heart rate (HR) did not change. Peak effect occurred 90 minutes after administration for the Cl, 30 to 120 minutes for PADP and SAP. The drug was well tolerated. This study confirms the acute beneficial hemodynamic effects of Captopril in patients with CHF refractory to conventional therapy. The possible mechanisms are discussed and the literature is reviewed.
