Soft-Tissue Sarcomas

June 01, 2016

The soft-tissue sarcomas are a group of rare but anatomically and histologically diverse neoplasms. This is due to the ubiquitous location of the soft tissues and the nearly three dozen recognized histologic subtypes of soft-tissue sarcomas.

Treatment of Localized Soft-Tissue Sarcoma: Lessons Learned

May 01, 2007

Over the past 30 years, there has been a migration away from amputation and radical ablative surgical procedures and toward more conservative, function-preserving surgery combined with radiation to treat extremity and body wall soft-tissue sarcomas. Efforts are now being focused on optimizing and streamlining treatment, including identifying subpopulations of patients who may be adequately treated by surgery alone. The goal of these efforts is to minimize the risks for short- and long-term treatment-related morbidity while maintaining excellent rates of local tumor control. This report will briefly review the progress made in these areas.

Combined-Modality Treatment for Operable Pancreatic Adenocarcinoma

March 01, 2005

Although in centers where pancreatectomy is performed frequently,associated morbidity and mortality rates have improved, long-term outcomesin pancreatic adenocarcinoma patients remain poor when surgeryis the sole therapeutic modality. The impact of adjuvant chemotherapyon survival in patients with localized pancreatic cancer remainsincompletely defined. The European Study Group for Pancreatic Cancer(ESPAC)-1 trial has suggested that overall survival rates are superiorwhen chemotherapy is added to surgery, even when regimens believedto be relatively ineffective in the treatment of advanced diseaseare used. The role of radiotherapy given with chemotherapy is alsounresolved, but chemoradiation continues to receive consideration inthe multimodality approach to localized pancreatic cancer. Enhancedcollaboration and increased involvement by pancreatic surgeons havehelped in the recruitment of pancreatic cancer patients for large-scalerandomized clinical trials in Europe and the United States. Many newerchemotherapeutic agents with efficacy in gastrointestinal cancers haveyet to be investigated in the adjuvant and neoadjuvant settings.

Irinotecan/Cisplatin in Advanced, Treated Gastric or Gastroesophageal Junction Carcinoma

May 02, 2002

We conducted a phase II study to assess the response rate and toxicity profile of the irinotecan (CPT-11, Camptosar) plus cisplatin combination administered weekly to patients with at least one previous chemotherapy for advanced adenocarcinoma of the stomach or gastroesophageal junction. Patients with histologic proof of adenocarcinoma of the stomach or gastroesophageal junction with adequate liver, kidney, and bone marrow functions were treated with 50 mg/m² of irinotecan plus 30 mg/m² of cisplatin, both administered intravenously 1 day a week for 4 consecutive weeks, followed by a 2-week recovery period.
