Another interesting study is known as, -Preoperative Tumor Volume Is Associated With Outcome In Malignant Pleural Mesothelioma- by Harvey I. Pass, MD, Barbara K. Temeck, MD, Karen Kranda, RN, Seth M. Steinberg, PhD, Irwin R. Feuerstein, MD – With the Thoracic Oncology Section,a Biostatistics and knowledge Management Section,b National Cancer Institute, Diagnostic Radiology Department,c Warren Magnusen Clinical Center, National Institutes of Health, Bethesda, Md. GENERAL THORACIC SURGERY – J Thorac Cardiovasc Surg 1998;115:310-318. Suggestions an excerpt: -Objectives: Our objective was to analyze the impact of preoperative and postresection solid tumor volumes on outcomes in 47 of 48 consecutive patients undergoing resection for malignant pleural mesothelioma who are treated prospectively and randomized to photodynamic therapy or no photodynamic therapy. Methods: From July 1993 to June 1996, 48 patients with malignant pleural mesothelioma had cytoreductive debulking to five mm or less residual tumor by extrapleural pneumonectomy (n = 25) or leurectomy/decortication (n = 23). Three-dimensional computed tomographic reconstructions of preresection and postresection solid tumor were prospectively performed additionally, the disease was staged postoperatively in accordance with the new International Mesothelioma Interest Group staging. Results: Median survival for everyone patients is 14.4 months (extrapleural pneumonectomy, 11 months; pleurectomy/decortication, 22 months; p2 = 0.07). Median survival for preoperative volume less than 100 was 22 months versus 11 months if a lot more than 100 cc, p2 = 0.03. Median survival for postoperative volume only 9 cc was 25 months versus 9 months if over 9 cc, p2 = 0.0002. Thirty-two of forty-seven (68%) had positive N1 or N2 nodes. Tumor volumes linked to negative nodes were significantly smaller (median 51 cc) as opposed to runners with positive nodes (median 166 cc, p2 = 0.01). Progressively higher stage was affiliated with higher median preoperative volume: stage I, 4 cc; stage II, 94 cc; stage III, 143 cc; stage IV, 505 cc; p2 = 0.007 for stage I versus II versus III versus IV. Patients with preoperative tumor volumes in excess of 52 cc had shorter progression-free intervals (8 months) as opposed to those 51 cc or less (11 months; p2 = 0.02). Conclusions: Preresection tumor volume is associated with T status in malignant pleural mesothelioma which enables it to predict overall and progression-free survival, and also postoperative stage. Large volumes are associated with nodal spread, and postresection residual tumor burden may predict outcome.- (J Thorac Cardiovasc Sufg 1998;115:310-8)
Another interesting study is, -Chemotherapy of diffuse malignant mesothelioma. Phase II trials of single-agent 5-fluorouracil and adriamycin- by Vernon J. Harvey MRCP, Dr. Maurice L. Slevin MRCP, Bruce A. J. Ponder PhD, MRCP, Anthony J. Blackshaw MA, MRCPath, Peter F. M. Wrigley PhD, FRCP – Cancer Volume 54, Issue 6, pages 961-964, 15 September 1984. Is an excerpt: -Abstract – Twenty consecutive patients which has a confirmed appropriate diffuse malignant mesothelioma belonging to the pleura or peritoneum, previously untreated with chemotherapy, were studied inside a Phase II trial of single-agent 5-fluorouracil. One partial response of Two or three years was seen. Eleven patients were cured with single-agent Adriamycin (doxorubicin) after progression on 5-fluorouracil, and the other partial response of 34 months was seen. It can be figured that 5-fluorouracil has minimal activity in diffuse malignant mesothelioma. Preliminary data report that Adriamycin has little activity as being a second-line agent.-
We all owe a debt of gratitude in order to those fine researchers with regards to work. In case you found any one of these excerpts helpful, please browse the studies into their entirety.
