Phase II Trial Using a Combination of Oxaliplatin, Capecitabine, and Celecoxib with Concurrent Radiation for Newly Diagnosed Resectable Rectal Cancer.

Lessons Learned: Colorectal cancers exhibit a high level of cyclooxygenase-2 (COX-2) expression with strong preclinical rationale for improved clinical outcomes with COX-2 inhibition. Celecoxib is a COX-2 inhibitor and we have shown that it can be safely combined with capecitabine and oxaliplatin as part of neoadjuvant treatment with radiation therapy (RT) in rectal cancer.There was a significant improvement in skin toxicity with this combination as compared with historical data.

INST OX-05-024: first line gemcitabine, oxaliplatin, and erlotinib for primary hepatocellular carcinoma and bile duct cancers: a multicenter Phase II trial.

Hepatocellular Carcinoma (HCC) incidence is increasing in the USA. Gemcitabine (G) and oxaliplatin (O) are active in HCC and biliary duct cancer (BDC). Erlotinib (E) is an EGFR tyrosine kinase inhibitor (TKI) with known activity against both.

Disease-specific survival for patients with multiple myeloma: significant improvements over time in all age groups.

This study analyzed the survival of patients with multiple myeloma. Surveillance, Epidemiology, and End Results (SEER) and Centers for Disease Control and Prevention (CDC) databases were queried to calculate myeloma cause-specific survival curves by the Kaplan and Meier product-limit method. The Cox proportional hazards model was used to assess univariate and multivariate predictors of myeloma cause-specific survival.

A phase II study of temsirolimus and erlotinib in patients with recurrent and/or metastatic, platinum-refractory head and neck squamous cell carcinoma.

Objectives: The epidermal growth factor receptor (EGFR) is a validated target in head and neck squamous cell carcinoma (HNSCC). In recurrent and/or metastatic (R/M) HNSCC, resistance to anti-EGFR therapy inevitably occurs. Downstream activation of the PI3K/Akt/mTOR pathway is an established resistance mechanism.

Anaplastic large cell lymphoma associated with breast implants.

A forty two years old woman with a history of bilateral breast augmentation for cosmetic reasons was presented for poor healing of the surgical site. Tissue and periprosthetic fluid were removed from the wound site revealing an atypical lymphoid infiltrate. Subsequently the patient developed axillary lymph adenopathy.

A phase I study of 5-azacytidine and erlotinib in advanced solid tumor malignancies.

Introduction: The epidermal growth factor receptor (EGFR) is a validated target in malignancy; however, patients with wild type EGFR obtain little sustained benefit from anti-EGFR monotherapy. Epigenetic therapy to reactivate tumor suppressor genes may enhance the anti-proliferative effect of erlotinib. This phase I study evaluated the combination of erlotinib and 5-azacytidine for safety and maximal tolerated dose (MTD).

Development of bronchiolitis obliterans organizing pneumonia with platinum-based chemotherapy for metastatic rectal cancer.

Bronchiolitis obliterans organizing pneumonia (BOOP) is an adverse event known to occur after cancer chemotherapy and radiotherapy. We present a case of a 47-year-old patient who was diagnosed with BOOP after treatment for metastatic rectal cancer with oxaliplatin/capecitabine/bevacizumab. Removal of oxaliplatin from the regimen and replacement with irinotecan resulted in a resolution of his pulmonary symptoms.

Clinicopathologic features of agranulocytosis in the setting of levamisole-tainted cocaine.

Levamisole is a known contaminant of cocaine and, via this route, has been associated with otherwise unexplained agranulocytosis. Levamisole is currently present in the majority of cocaine samples seized by the US Drug Enforcement Agency. We identified 20 cases of unexplained agranulocytosis in our practice locations of Albuquerque, NM, and Vancouver, Canada.

Epstein-Barr virus-associated inflammatory pseudotumor of the spleen: report of two cases and review of the literature.

We report two rare examples of Epstein-Barr virus (EBV)-associated inflammatory pseudotumor of the spleen. One patient presented with night sweats, abdominal pain, and weight loss and was found to have a splenic mass on CT scan suspected of lymphoma. The splenic mass in second patient was found incidentally at the time of work up for kidney stones.

Breast disease: benign and malignant.

Breast diseases, both benign and malignant, are common. Typically, young women present with more benign pathologies; however, breast malignancies can occur in young women, especially in those harboring mutations in the BRCA genes, other inherited genetic syndromes associated with increased risk of breast cancer, or familial predisposition for breast cancer. In all women aged 40 and over presenting with abnormalities of the breast, a primary breast cancer should be ruled out because it is the leading cancer among women in developed countries.

Hypokalemia secondary to capecitabine: a hidden toxicity?

Background: Hyopkalemia is a listed toxicity in the capecitabine (Xeloda(R); Roche, Nutley, NJ) package insert. However, the incidence and severity of this toxicity is not known.

Methods: We performed a retrospective evaluation of hypokalemia in 77 patients, who received capecitabine for gastrointestinal malignancies between April 2002 and November 2004.
