Severity, risk factors, and physician practices in the management of anemia during concurrent chemoradiation for head and neck carcinoma
Authors: Tanvetyanon Tawee , Choudhury Abdul M. 
Published: March 2006

AbstractBACKGROUNDAnemia is a well‐recognized complication of concurrent chemoradiation therapy for head and neck carcinoma. It impairs quality of life and many studies also have reported an association between anemia and increased tumor recurrence and decreased long‐term survival. In the current study, the authors attempted to identify the severity, risk factors, and physician practices in the management of anemia.METHODSMedical records of those patients receiving concurrent chemoradiation for head and neck carcinoma between 1999–2003 were reviewed. The average weekly nadir hemoglobin level (AWNH) was defined as the mean value of the lowest hemoglobin concentration in each week. Independent predictors for an AWNH < 11 g/dL were identified using multivariable logistic regression analyses.RESULTSSeventy‐two patients were included in the current study, 66.7% of whom had unresectable disease. The overall median survival was 402 days. At baseline, 76.4% (95% confidence interval [95% CI], 66.3–86.4%) of patients already had a hemoglobin level < 13.5 g/dL. The hemoglobin level dropped 2.5 ± 1.9 g/dL during concurrent chemoradiation, resulting in 95.8% of patients having a hemoglobin level < 13.5 g/dL at the end of the observation period. Blood was transfused to 24 patients (33.3%); erythropoietin or darbepoietin was administered to 2 patients (2.7%). The mean lowest hemoglobin threshold of transfusion was 7.3 ± 1.0 g/dL. The cumulative percentage of patients who received a transfusion reached 50% when the mean nadir hemoglobin level was 7.4 g/dL. Independent predictors of an AWNH < 11.0 g/dL were low baseline hemoglobin and receiving multiple concurrent chemotherapeutic agents, with relative risks of 13.6 and 1.8, respectively (95% CI,1.9–93.9 and 1.1–3.1, respectively).CONCLUSIONSAnemia is prevalent in patients undergoing treatment for head and neck carcinoma and can be severe with concurrent chemoradiation therapy. However, the intensity of anemia management is low. A low baseline hemoglobin level and the reception of multiple concurrent chemotherapeutic agents are considered to be the main risk factors of anemia. Cancer 2006. © 2006 American Cancer Society.
Metastatic patterns in adenocarcinoma

Published: March 2006

AbstractBACKGROUNDUnique metastatic patterns cited in the literature often arise from anecdotal clinical observations and autopsy reports. The authors analyzed clinical data from a large number of patients with histologically confirmed, distant‐stage adenocarcinoma to evaluate metastatic patterns.METHODSTumor registry data were collected between 1994‐1996 on 11 primary tumor sites and 15 metastatic sites from 4399 patients. The primary and metastatic sites were cross‐tabulated in various ways to identify patterns, and the authors developed algorithms by using multinomial logistic regression analysis to predict the locations of primary tumors based on metastatic patterns.RESULTSThree primary tumors had single, dominant metastatic sites: ovary to abdominal cavity (91%), prostate to bone (90%), and pancreas to liver (85%). The liver was the dominant metastatic site for gastrointestinal (GI) primary tumors (71% of patients), whereas bone and lung metastases were noted most frequently in non‐GI primary tumors (43% and 29%, respectively). In a study of combinations of liver, abdominal cavity, and bone metastases, 86% of prostate primary tumors had only bone metastases, 80% of ovarian primary tumors had only abdominal cavity metastases, and 74% of pancreas primary tumors had only liver metastases. A single organ was the dominant source of metastases in 7 sites: axillary lymph node from the breast (97%), intestinal lymph node from the colon (84%), thoracic lymph node from the lung (66%), brain from the lung (64%), mediastinal lymph node from the lung (62%), supraclavicular lymph node from the breast (51%), and adrenal gland from the lung (51%).CONCLUSIONSThe algorithms that the authors developed achieved a cross‐validated accuracy of 64% and an accuracy of 64% on an 1851‐patient independent test set, compared with 9% accuracy when a random classifier was used.

Expression of Bcl‐2 in gastrointestinal stromal tumors

AbstractBACKGROUNDThe natural history of gastrointestinal stromal tumor (GIST) has been revolutionized by imatinib mesylate (imatinib) therapy. Before imatinib, Bcl‐2 expression in GIST was associated with a worse prognosis or added no additional prognostic value. To the authors' knowledge, the current study is the first to evaluate Bcl‐2 expression in pre‐imatinib GIST tissue samples as a prognostic marker of progression‐free survival (PFS) time in patients treated with imatinib.METHODSThe cases of 81 patients with GIST who were evaluated between December 15, 2000 and September 1, 2001 were retrospectively reviewed. Clinicopathologic variables were reviewed. GIST cell morphology and patterns of Bcl‐2 expression were described. The methods of Kaplan–Meier and the Cox proportional hazards regression model were used for statistical analysis.RESULTSSixty‐one (75%) patients had tumors that expressed Bcl‐2, and 20 (25%) patients had tumors that were negative for Bcl‐2. All epithelioid tumors (n= 12) expressed Bcl‐2 and tumors with mixed morphology exhibited Bcl‐2 expression in the epithelioid component. A trend toward longer PFS for patients whose tumors expressed Bcl‐2 at a greater immunohistochemical intensity was observed (20.6 mos for no Bcl‐2 expression; 28.3 mos for 1++Bcl‐2 expression; 31.9 mos for 1.5++Bcl‐2 expression; 40.8 mos for 2++Bcl‐2 expresssion; and 35.9 mos for 3++Bcl‐2 expression).CONCLUSIONSIn contrast to studies performed in the preimatinib era, in which Bcl‐2 was found to be a negative prognostic indicator, the current study suggests a trend toward better PFS with increasing Bcl‐2 expression level in GISTs from patients subsequently treated with imatinib. Larger studies may help elucidate the influence of Bcl‐2 expression on PFS after therapy with imatinib. Cancer 2006. © 2006 American Cancer Society.
