Abstract

Purpose: Patients movement and Organs mobility during Three Dimensional Conformational Radiotherapy (3D-CRT) may introduce errors especially during the treatment delivery, random and systematic errors are one of the most accurate errors. In this work we implanted a method to determinate the Clinical Target Volume (CTV) to Planning Target Volume (PTV) margins. The aim of this study is to reduce these errors probability by the evaluation of the optimal for CTV-PTV margin by studying the corrected values of deviations for HNC at the Mohammed VI cancer treatment centre treated between 2019 and 2021. Material and Method: The study consists on creating a DATA base containing spatial movement of study group of 100 patients following the treatment machine axis Vrt, Lng, and Lat directions during the first four fractions. This study is done by Monaco (Version 5.11.02, Elekta, Stockholm Sweden) treatment planning system V 5.11.02 (TPS) and Mosaiq V 2.0 involving iViewGT R3.4.0 and XVI R5.0.3 on board imaging systems by Elekta Infinity Treatment Machine (Elekta Ltd, Crawley, UK). The patients were choosing randomly during the study and archived in a DATA base to collect the random and systematic errors, the root of the sum of the squares for the doubled value of method uncertainty based on the Van Herk and AL equation of PTV to CTV determination, Stroom's model of Tumour Control Probability (TCP) and ICRU-50 formalism. Included: The random choice was made to detect maximum of errors possible and to optimize the value of main function for errors margins obtained through the study. Each patient was controlled by Kv images (iViewGT R3.4.0 and XVI R5.0.3 on board imaging systems) to determinate the gap between the dosimetry-CT acquisition and the treatment session. The DATA analysis was made calculating about 400 parameters to obtain the main Function and standard deviation for every patient. Results: CTV-PTV margin collected DATA was obtained by the correction values obtained by imaging system before treatment gave us a Mean (M) deviation function, the systematic errors (S) value and random errors (s) respectively: 4.04 mm, 0.40 mm and 6.35 mm. the result obtained by the application of this values in the Van Herk equation for CTV-PTV margin was 5.7 mm. Conclusion: The value calculated allowed us to have a validation of our quality treatment for three dimensional radiotherapy HNC and make sure that at Mohammed VI cancer treatment centre the norms and recommendations of radiotherapy treatments delivery are respected.

Abstract

Intracystic papillary carcinoma of the breast in men is an extremely rare disease with an excellent prognosis. Here, we report a new case of intracystic papillary carcinoma of the breast in a 79- year-old man. He was admitted in our department for a painless cystic lump in the left breast. He underwent a mastectomy without lymph node dissection. The pathologic examination objectified an intracystic papillary carcinoma without an invasion. There are no clear guidelines about the management of IPC. Most publications reinforce the importance of surgery is the mainstay of treatment, which can be either conservation or mastectomy

39. TUMEUR D’ASKIN. A PROPOS DE HUIT OBSERVATIONS

Author

Abstract

La tumeur d’Askin est une tumeur neuroectodermique primitive de la région thoracopulmonaire. Elle est rare représentant 6.5% des sarcomes, survenant chez l’enfant et le sujet jeune. Son pronostic est très défavorable ; la survie à 2 ans étant de 38% [1]. Le traitement est basé sur la chimiothérapie néo-adjuvante, suivie d'une chirurgie radicale si possible et/ou d'une irradiation, puis d'une chimiothérapie adjuvante selon la réponse de la tumeur à la chimiothérapie initiale [2,3] .Nous rapportons 8 cas de tumeurs d’Askin traités dans notre service. C’est une étude rétrospective de 8 cas de tumeurs d’Askin colligés au centre d’oncologie Ibn Rochd de Casablanca, durant la période 1998 -2003. Nous rapportons les résultats de notre expérience ainsi qu’une revue de la littérature., Journal Marocain des Sciences Médicales, Vol. 18, No 3 (2013)

Abstract

We report a case of adrenal metastasis from colorectal cancer in a 54-year-old woman. Nine months after resection for advanced rectal carcinoma, a computed tomography scan revealed bilateral adrenal metastasis. The level of serum carcinoembryonic antigen was normal. A bilateral adrenalectomy was performed after chemotherapy. Histopathological examination showed adenocarcinoma, compatible with metastasis from the rectal cancer. Adrenal metastasis should be considered in the patients’ follow-up for colorectal cancer.

Abstract

Le Carcinosarcome du sein est un cancer rare et agressif. Nous rapportons un cas de Carcinosarcome du sein droit chez une patiente de 51 ans, célibataire, diabétique type II, traitée par chirurgie première, six cycles de chimiothérapie en adjuvant puis radiothérapie sur la paroi droite. La patiente est en rémission complète après un recul de 12 mois. Le but de notre travail est de rapporter les caractéristiques anatomopathologiques, thérapeutiques et enfin pronostiques de cette entité rare., Journal Marocain des Sciences Médicales, Vol. 17, No 3 (2010)
