Forty-nine patients with metastatic nonanaplastic thyroid carcinoma were treated over a 10-year period. Five successive chemotherapeutic protocols were used: a combination of doxorubicin, etoposide, 5-fluorouracil and cyclophosphamide; elliptinium acetate; doxorubicin; cisplatin; and the combination of doxorubicin and cisplatin. Results obtained with the different protocols were very disappointing, with only two objective responses (3%). Phase II trials with new chemotherapeutic agents are warranted in selected cases of nonanaplastic metastatic thyroid carcinoma.

Among patients suffering from nonseminomatous germ-cell tumor, with a poor prognosis, a subset underwent respiratory failure and died very early in the course of their treatment. Between 1982 and 1989, 11 out of 56 such patients (20%) died within the first 5 weeks of chemotherapy. The clinical, radiological, biological and infectious characteristics of these patients were analyzed. Nine patients had extensive pulmonary metastases and the 2 others presented a bulky mediastinal mass with pleural effusion. All patients experienced acute respiratory distress during chemotherapy and underwent mechanical ventilation. All patients were febrile, and septicemia was documented in 7 cases. WHO grade 4 and grade 1-2 renal toxicities occurred in 3 and 4 patients respectively. There was no tumor lysis syndrome. All patients died within 35 days from the start of therapy; 4 were autopsied. These 11 patients represent a clinical entity, having what we called super-high-risk germ cell tumors. Early death is related to pulmonary distress within the first 5 weeks of therapy. The origin of the pulmonary distress is multifactorial: bulky disease of the chest, infection, and interstitial fibrosis. Immediate full-dose standard chemotherapy in association with intensive supportive care is recommended in the management of these patients.

In order to define prognostic factors for advanced stage of nonseminomatous germ cell tumors (NSGCT) of the testis, the authors reviewed 84 patients treated from 1978 through 1985. The survival rate was 51% at 3 years. Patients with elevated seric levels of human chorionic gonadotropin (HCG) and/or alpha-fetoprotein (AFP), or the presence of an abdominal mass had significantly worse survival. Only HCG and AFP levels retained their significance when multivariate Cox analysis was performed. The probability that a patient achieves a complete remission (CR) was assessed by a function of certain patient characteristics using a multivariate logistic regression analysis. The significant variables were a function of HCG and AFP values. Since both variables are related to the CR rate and survival the authors define the obtention of a CR as a unique outcome of interest. The probability of a CR greater than 70% adequately separates the patients into two prognostic subgroups. This model currently is being used to enrole NSGCT patients in a prospective modulated clinical trial according to these prognostic factors.

Adrenal vein sampling (AVS) is essential in differentiating unilateral from bilateral sources of aldosterone excess in primary aldosteronism (PA). However, its ability to predict blood pressure (BP) improvement after adrenalectomy has not been well studied. This is a retrospective observational study of 119 patients who underwent AVS by sequential technique followed by adrenalectomy for PA at the Hospital of the University of Pennsylvania from 1997 to 2015. Median age was 52 years (interquartile range 44-59), 67% were male and median duration of hypertension was 10 (interquartile range 6-20) years. A total of 76% and 90% of patients experienced BP improvement at 0-6 months or at any time point after surgery, respectively. Lateralization index (LI) >8, but not the presence of contralateral suppression, was significantly associated with BP improvement after surgery by multivariate logistic regression analysis adjusted for potential confounders (odds ratio (95% confidence interval): 17.1 (1.7-171.6) and 6.39 (0.06-641.8), respectively). A prediction score was created by covariates that was significantly associated with BP improvement in logistic regression analysis (duration of hypertension, body mass index, preoperative systolic BP and number of antihypertensive medications). Receiver-operating characteristic curve analyses showed that the addition of LI >8 to the score increased its ability to predict BP improvement (area under the curve 0.73-0.80). In conclusion, LI is useful in predicting improvement in BP after adrenalectomy for PA. The results of this study suggest that patients with long-standing severe hypertension may still benefit from surgery if LI >8.

In order to define the prognostic factors for metastatic renal carcinoma, we reviewed 134 patients who were treated from 1971 through 1986. Survival rates were 72, 45, and 25% at 6, 12, and 18 months, respectively. Seventeen variables were tested using the logrank test. Improved survival was correlated with normal performance status, and an absence of fever, weight loss, hepatic metastasis, and lung metastasis (or, if lung metastasis was present, less than 2 cm in diameter and limited to one site), a disease-free interval, sedimentation rate less than 100, and renal surgery. Four variables retained significant value in the multivariate analysis: hepatic metastasis, lung metastasis, disease-free interval, and a variable combining the sedimentation rate and the weight loss (SWRL). Predictive survival rates based on these variables were calculated from the Cox model. Six subgroups of patients were identified. The estimation of survival is clinically of value for future phase II trials of chemotherapy in patients with adult metastatic renal carcinoma.
