One interesting study is termed, -Prognostic Analysis of Clinicopathologic Factors in 49 Patients With Diffuse Malignant Peritoneal Mesothelioma Treated With Cytoreductive Surgery and Intraperitoneal Hyperthermic Perfusion- – by Marcello Deraco, Daisuke Nonaka, Dario Baratti, Paolo Casali, Juan Rosai, Rami Younan, Andreola Salvatore, Antonello D. Cabras AD and Shigeki Kusamura – Annals of Surgical Oncology Volume 13, 2nd, 229-237. The following is an excerpt: -Abstract – Background – Diffuse malignant peritoneal mesothelioma (DMPM) is usually a subset of peritoneal mesothelioma which includes a poor clinical outcome. We performed a prognostic analysis within a cohort of DMPM patients treated homogeneously by cytoreductive surgery and intraperitoneal hyperthermic perfusion (IPHP). Methods – Forty-nine DMPM patients who underwent 52 consecutive procedures were enrolled towards the study. Cytoreductive surgery was performed using the peritonectomy technique, and also the IPHP was performed with cisplatin plus doxorubicin or cisplatin plus mitomycin C. We assessed the correlation belonging to the clinicopathologic variables (previous surgical score, age, sex, performance status, previous systemic chemotherapy, carcinomatosis extension, completeness of cytoreduction, IPHP drug schedule, mitotic count [MC], nuclear grade, and biological markers [epidermal growth factor receptor, p16, matrix metalloproteinase 2 and matrix metalloproteinase 9]) with overall and progression-free survival.
Results – The mean age was 52 years (range, 22-74 years). The mean follow-up was 20.3 months (range, 1-89 months). In connection with the biological markers, the rates of immunoreactivity of epidermal growth factor receptor, p16, matrix metalloproteinase 2, and matrix metalloproteinase 9 were 94%, 60%, 100%, and 85%, respectively. The strongest factors influencing overall survival were completeness of cytoreduction and MC, whereas those for progression-free survival were performance status and MC. No biological markers were estimated to be of prognostic value.
Conclusions – Completeness of cytoreduction, performance status, and MC look like they’re the ideal determinants of outcome. These data warrant confirmation from a further prospective formal trial. No biological markers presented a significant correlation using the outcome. The overexpression of epidermal growth factor receptor, matrix metalloproteinase 2, and matrix metalloproteinase 9 and absent or reduced expression of p16 could possibly be linked to the underlining tumor kinetics of DMPM and warrant further investigation to methods.
Another interesting study is known as, -A randomised controlled trial of intervention site radiotherapy in malignant pleural mesothelioma.- By O’Rourke N, Garcia JC, Paul J, Lawless C, McMenemin R, Hill J. – Radiother Oncol. 2007 Jul;84(1):18-22. Epub 2007 Jun 22. At this point is an excerpt: -Abstract – BACKGROUND AND PURPOSE: To gauge the potency of radiotherapy in preventing tumour seeding after chest drain or pleural biopsy in patients with malignant mesothelioma in order to determine, if tract metastases appear, whether or not they are tender or troublesome to patients.
PATIENTS And techniques: Patients which has a histological proper diagnosis of pleural mesothelioma with an invasive procedure around the preceding A 3 week period were stratified by age, performance status and treatment centre. Randomisation was performed between immediate drain site radiotherapy 21Gy in three fractions (XRT arm) or best supportive care (BSC) with follow-up to One year. Patients were motivated to complete questionnaires on treatment toxicity and on symptoms from tract metastases detected.
RESULTS: Sixty-one patients were recruited from two centres between 1998 and 2004; 56 men, 5 women, median age 70. 31 were allocated to drain site radiotherapy. Seven patients developed tract metastases belonging to the drain site (four XRT arm, three BSC) and 4 developed metastases involving subsequent procedures at other sites (three XRT, one BSC). Two patients each developed two tract metastases. On the 12 metastases, nine overlay the prior drain site but three were beside the site. No statistically significant difference was discovered inside the chances of tract metastasis of the drain site between your arms (p=0.748).
CONCLUSIONS: Prophylactic drain site radiotherapy in malignant pleural mesothelioma would not reduce the incidence of tumour seeding by way of the margin shown by previous studies.
Another interesting study is referred to as, -The valuation on chest computer tomography and cervical mediastinoscopy during the preoperative assessment of patients with malignant pleural Mesothelioma- by J. Hugo Schouwink, MD, Leo Schultze Kool, MD, PhD, Emiel J. Rutgers, MD, PhD, Frans A. N. Zoetmulder, MD, PhD, Nico van Zandwijk, MD, PhD, Marc J. v.d. Vijver, MD, PhDd, Paul Baas, MD, PhD – Ann Thorac Surg 2003;75:1715-1718. Here is an excerpt: -BACKGROUND: Patients with localized malignant pleural mesothelioma (MPM) can be viewed as for surgical resection with or without additional treatment. Just for this approach it can be important for select patients without mediastinal lymph node involvement. Within this study cervical mediastinoscopy (CM) is weighed against computer tomography (CT) scanning for their diagnostic accuracy in assessing mediastinal lymph nodes during preoperative workup.
METHODS: Computer tomography scans belonging to the chest and CM were performed in 43 patients with proven unilateral MPM. The CT scans were reviewed by one radiologist as well as 2 chest physicians. At CM the lymph node samples were stripped away from stations Naruke 2, 3, 4, and 7. Computer tomography and CM results were compared with final histopathologic findings obtained at thoracotomy or, when this has not been performed, at CM.
RESULTS: Computer tomography scanning revealed pathologic enlarged lymph nodes by using a shortest diameter that is at least 10 mm in 17 of 43 patients (39%). There seemed to be histopathologic evidence of lymph node metastases at CM in 11 for these patients (26%). This ended in a sensitivity of 60% and 80%, a specificity of 71% and 100%, plus a diagnostic accuracy of 67% and 93% for CT and CM, respectively.
CONCLUSIONS: Cervical mediastinoscopy may be a valuable diagnostic steps involved in patients with MPM that happen to be considered candidates for surgical-based therapy. Outcomes of CM are certainly more reliable than the others obtained by CT scanning. Our data confirm link between previous studies reporting that mediastinal lymph node involvement is a frequent event in MPM.-
