Purpose To prospectively assess the impact of treatment with cisplatin alone or in combination with topotecan (CT) on quality of life (QOL) in patients with advanced or recurrent cervical cancer, and to explore the prognostic value of baseline QOL scores. Patients and Methods Patients entered on Gynecologic Oncology Group (GOG) Protocol 179 were expected to complete QOL assessments at four time points using Functional Assessment of Cancer Therapy–General (FACT-G), Cervix subscale (Cx subscale), FACT/GOG–Neurotoxicity subscale (NTX subscale), Brief Pain Inventory (BPI), and UNISCALE (UNI). Adjusting for patient age, baseline scores, and effects of time, we longitudinally examined treatment effect on QOL during and after chemotherapy. Results Among patients randomly allocated to receive cisplatin (n = 146) or CT (n = 147), there were no statistically significant differences in QOL up to 9 months after randomization despite more hematologic toxicity in the combination arm. QOL assessments were completed at rates of 98%, 85%, 68%, and 59%, respectively, for the four time points, with similar rates and reasons for nonparticipation between regimens. Baseline FACT-G (P = .0016) and BPI (P = .0001) scores were significantly associated with patient age; older patients had better QOL and less pain. Baseline UNI was positively correlated with FACT-G (r = 0.66; P < .001) and Cx subscale (r = 0.29; P < .001), and negatively related to BPI (r = −0.41; P < .0001). Baseline FACT-Cx (FACT-G + Cx subscale) was associated with survival. Conclusion Despite increased toxicity, CT did not significantly reduce patient QOL when compared with cisplatin alone. Patient-reported QOL measures may be an important prognostic tool in advanced cervix cancer.

Purpose On the basis of reported activity of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) or topotecan plus cisplatin in advanced cervix cancer, we undertook a randomized trial comparing these combinations versus cisplatin alone, to determine whether survival is improved with either combination compared with cisplatin alone, and to compare toxicities and quality of life (QOL) among the regimens. Patients and Methods Eligible patients were randomly allocated to receive cisplatin 50 mg/m2 every 3 weeks (CPT); cisplatin 50 mg/m2 day 1 plus topotecan 0.75 mg/m2 days 1 to 3 every 3 weeks (CT); or methotrexate 30 mg/m2 days 1, 15, and 22, vinblastine 3 mg/m2 days 2, 15, and 22, doxorubicin 30 mg/m2 day 2, and cisplatin 70 mg/m2 day 2 every 4 weeks (MVAC). Survival was the primary end point; response rate and progression-free survival (PFS) were secondary end points. QOL data are reported separately. Results The MVAC arm was closed by the Data Safety Monitoring Board after four treatment-related deaths occurred among 63 patients, and is not included in this analysis. Two hundred ninety-four patients enrolled onto the remaining regimens: 146 to CPT and 147 to CT. Grade 3 to 4 hematologic toxicity was more common with CT. Patients receiving CT had statistically superior outcomes to those receiving CPT, with median overall survival of 9.4 and 6.5 months (P = .017), median PFS of 4.6 and 2.9 months (P = .014), and response rates of 27% and 13%, respectively. Conclusion This is the first randomized phase III trial to demonstrate a survival advantage for combination chemotherapy over cisplatin alone in advanced cervix cancer.

AbstractIn the absence of distant disease, the pathologic diagnosis of malignancy in pheochromocytoma or paraganglioma is impossible. In an effort to establish the true incidence of recurrence in this disease, we have analyzed long‐term follow‐up (average, 15.8 years) of 98 patients who underwent complete resection of localized, noninvasive, histologically‐benign pheochromocytomas and paragangliomas at our institution between 1960 and 1976.Eighty‐eight patients had nonfamilial, sporadic pheochromoctyoma/ paraganglioma. Nine had multiple endocrine neoplasia (MEN) type 2 (2A: 7, 2B: 2), and 1 had familial pheochromocytoma. Seventy‐nine patients had single pheochromocytomas; 10 had single extraadrenal tumors (paragangliomas); and 9 had multicentric or bilateral adrenal tumors.Six patients (6.5%) developed recurrent pheochromocytoma after documentation of normal postoperative urinary catecholamine levels. One of these patients had MEN 2A. The recurrences developed at intervals from 5 to 13 years following initial resection. These were distant in 3 patients, local in 2, and both local and distant in a single patient. None of the recurrences occurred in the 13 patients who, on pathologic rereview, had either local or vascular invasion. No paraganglioma recurred.Life‐long follow‐up of all patients who have had pheochromocytomas or paragangliomas resected is mandatory.

Long QT syndrome is a malfunction of cardiac ion channels resulting in impaired ventricular repolarization that can lead to a characteristic polymorphic ventricular tachycardia known as torsades de pointes. Stressors, by increasing sympathetic tone, and drugs can provoke torsade de pointes, leading to syncope, seizures, or sudden cardiac death in these patients. Beta blockade, implantation of cardioverter defibrillators, and left cardiac sympathetic denervation are used in the treatment of these patients. However, these treatment modalities do not guarantee the prevention of sudden cardiac death. Certain drugs, including anesthetic agents, are known to contribute to QT prolongation. After reviewing the literature the authors give recommendations for the anesthetic management of these patients in the perioperative period.

AbstractA number of surgical methods, including use of the long intestinal tube, have been designed to decrease the incidence of recurrent small bowel obstruction. The aim of the present study was to review the indications, morbidity, and long‐term results of the long intestinal tube at the Mayo Clinic. During the 12‐year period 1981–1992, 47 patients had such tubes placed. The patients formed a complex surgical group: 46 patients had previously undergone at least one laparotomy (median 4, range 1–10); 41 patients had been hospitalized at least once for small bowel obstruction (median 3, range 1–15); and all 41 of these patients had undergone at least one previous laparotomy for obstruction (median 2, range 1–7). Eleven patients had a history of inflammatory bowel disease, and eight had a history of irradiation. In addition to dense adhesions in 46 patients, operative findings included large bowel tumors in six patients, intraperitoneal carcinomatosis in four, intraabdominal abscess in four, and small bowel stricture in three. Twenty patients required either a small bowel or large bowel resection, and three had a stoma fashioned. Only one case of morbidity (tube retraction) was related to tube placement. Among the 36 patients with complete follow‐up, nine patients developed episodes of recurrent adhesional small bowel obstruction after a mean follow‐up of 48 months, although only one required laparotomy. Of the remaining 11 patients it is known that two developed small bowel obstruction, one of whom required laparotomy. Use of the long intestinal tube has generally been reserved for surgically complex cases. In light of the diverse and complicated nature of the patients in this series, the long‐term reoperation rate for adhesional small bowel obstruction appears to be low.
