Is the delay in starting postoperative radiotherapy a key factor in the outcome of advanced (T3 and T4) laryngeal cancer?

OBJECTIVE: To identify factors influencing the outcome of postoperative radiotherapy in patients with advanced laryngeal cancer. DESIGN: The files of 44 patients with advanced laryngeal cancer who were treated by surgery followed by radiotherapy (24 with pT3 and 20 with pT4) were reviewed. Median delay in starting radiotherapy was 50 days (range, 19-150 days). Treatment variables, in addition to certain patient and tumor characteristics, were analyzed in terms of locoregional control and survival. SETTING: Major referral tertiary center in central Israel. RESULTS: Locoregional control rates were 86% and 81% at 2 and 5 years, respectively, and corresponding survival rates were 82% for both. Only nodal involvement retained statistical significance for both locoregional control as well as survival on multivariate analysis (P = 0.0009 and P = 0.0004, respectively). CONCLUSIONS: This is the first study showing that delay in postoperative radiotherapy in advanced laryngeal cancer is not a significant predictor of locoregional control or survival in advanced laryngeal cancer. Only lymphatic spread was found to have a significant influence on treatment outcome.

Older age and second skin cancer as prognostic factors in localized malignant melanomas.

Of the numerous prognostic factors for patients with localized malignant melanoma (LMM), none is superior to the simple parameter of tumor thickness. The aim of the present study was to better define prognostic factors for this disease. Between January 1992 and December 1994, 188 consecutive patients with LMM were treated at the Rabin Medical Center. Patient and tumor characteristics were retrospectively examined as potential prognostic factors. Patients (n=173) who had had at least two-year follow-up were included in the overall survival (OS) analysis, and 159 patients for whom accurate data on recurrent disease were available were included in the disease-free survival (DFS) analysis. At a median follow-up of 85 months (range 24-114), 48 patients (30%) had recurrent disease which resulted in death in 35 (20%). The five-year OS and DFS rates for the entire group were 82 and 72%, respectively. On univariate analysis, female gender, age younger than 75 years, metachronous or synchronous second skin cancer (including melanoma), light skin color, tumor thickness and TNM stage were predictive of both OS and DFS. Tumor location and ulceration, correlated with only one endpoint, OS or DFS, respectively. On multivariate analysis, three factors retained statistical significance with regard to both OS and DFS: tumor thickness (p=0.000 for both), second skin cancer (p=0.02 for both), and age (p=0.04 for both). Alongside the well-established predictive factor of tumor thickness in LMM, older age and the presence of a second skin cancer also have prognostic significance. The prognostic importance of the latter is reported here for the first time.

Classical Kaposi sarcoma: prognostic factor analysis of 248 patients.

BACKGROUND: Classical Kaposi sarcoma (CKS) is a rare indolent neoplasm that is particularly prevalent among Jews of Ashkenazi and Mediterranean origin. Data regarding prognostic factors for CKS are scarce. The aim of the current retrospective analysis was to better define prognostic subgroups among patients with CKS. METHODS: Between 1960 and 1995, 248 consecutive patients with CKS were treated at the Rambam and Rabin Medical Centers in Israel. Although treatment options included local excision, radiotherapy, and chemotherapy, observation alone was used for 31% of patients. For prognostic factor analysis, disease progression was classified as any progression and dissemination, and progression-free survival was calculated for each. RESULTS: At a median follow-up of 20 months, four patients (1.6%) died of CKS. Of the patients eligible for analysis, 94 of 220 (39%) had any progression and 23 of 120 (18%) had dissemination. Only 8 of 202 (4%) had visceral spread. On univariate analysis, age was a statistically significant prognostic factor for any progression (P = 0.04), whereas immunosuppression and visceral involvement at presentation had only borderline significance. Immunosuppression was the only prognostic factor for dissemination (P = 0.003). On multivariate analysis, both age and immunosuppression were significant prognostic factors for any progression (P = 0.001 and 0.01, respectively). Immunosuppression was also predictive of dissemination (P = 0.006). CONCLUSIONS: Immunosuppression and older age (50 years and older) are strongly associated with poorer outcome among CKS patients. The two end points used in this study may be used for future prognostic factor analyses.

Advanced non-small cell lung cancer: induction chemotherapy and chemoradiation before operation.

BACKGROUND: Induction chemotherapy before operation is beneficial for patients with advanced locoregional non-small cell lung cancer. However, no optimal regimen has been established. This study assesses feasibility, response, resectability, and survival of chemotherapy followed by chemoradiation before operation in patients with non-small cell lung cancer. METHODS: Fifty-seven stage IIIA and selected IIIB patients with non-small cell lung cancer received 2/3 cycles of cisplatin and oral etoposide, followed in 3/4 weeks by chemoradiation with daily cisplatin before each radiation fraction. Patients achieving a resectable status underwent operation. RESULTS: Response to induction treatment was documented in 73%; 69% achieved a resectable status and 53% underwent operation. Median survival was 16 months. The 1-, 2-, and 3-year survival rates were 65%, 35% and 22%, respectively. There was no difference in survival between stage IIIA and IIIB disease. Myelotoxicity was moderate to severe (grade III/IV in 61% of patients). Three patients died of late complications of pneumonectomy. CONCLUSIONS: Our presurgery chemotherapy and chemoradiation protocol yields high response and resectability rates, with moderate to severe myelotoxicity. Pneumonectomy is associated with a relatively high rate of late complications.

Male breast carcinoma in Israel: higher incident but possibly prognosis in Ashkenazi Jews.

BACKGROUND: Little information is available regarding male breast carcinoma. However, cumulative data have suggested a propensity for the disease among Ashkenazi Jews. Because Ashkenazi Jews comprise one of the major ethnic groups in Israel, the authors conducted a local study to shed more light on the features of this rare disease. METHODS: From 1960 to 2000, 131 men with breast carcinoma were treated at the Rabin Medical Center or the Rambam Medical Center, and, from 1980 to 1997, 470 patients with this diagnosis were recorded in the Israel Cancer Registry. These two data bases were used to analyze the epidemiologic and clinicopathologic characteristics of male breast carcinoma in Israel. RESULTS: Seventy-eight percent of the 131 Jewish patients were Ashkenazi. Most of their clinical characteristics were similar to those of their Sephardic counterparts. However, there was a statistically significant difference in the pattern of comorbidity between these groups (P = 0.000), and there was a trend toward a younger age at onset and more advanced tumor stage at the time of diagnosis for the Sephardim. It also was found that Sephardic origin was associated with poorer outcome (P = 0.03). Analysis of the Cancer Registry data base revealed an 80% increase in the risk of the disease for Ashkenazi Jews compared with Sephardic Jews (odds ratio, 1.8; 95% confidence interval, 1.4-2.3; P = 0.001). Survival analysis from this source suggested a poorer outcome for Sephardic Jews compared with Ashkenazi Jews (62% vs. 64.3% estimated 5-year survival rates, respectively; P = 0.08). CONCLUSIONS: Analyses of two independent data bases, patient charts, and a cancer registry indicate that breast carcinoma seems to be more prevalent among Ashkenazi Jewish men. At the same time, affected Ashkenazi patients may have a more favorable outcome than their Sephardic counterparts.

[Rising CA-125 levels in a patient with ovarian cancer are not always indicative of disease recurrence].

UNLABELLED: A 64-year-old woman was diagnosed as suffering from ovarian cancer. At that time, in 1984, she was treated with chemotherapy and complete remission was achieved. The disease recurred 2.5 years later and chemotherapy was delivered again. The patient remained disease free for 9 years. At that point a routine blood examination revealed a high serum level of the marker CA-125. A second recurrence of ovarian cancer was assumed. Nonetheless, work up revealed that the rise in CA-125 was related to the presence of a non-Hodgkins lymphoma (NHL). CONCLUSIONS: This case together with our review of the literature highlights the emerging roll of the CA-125 marker in the diagnosis and follow-up of non-Hodgkins lymphoma. Our case also illustrates that physicians should be aware of the fact that markers may be misleading.
