In every patient, two targets were defined, clinical target volume (CTV) including the prostate and seminal vesicles (CTV-PSV) and CTV including pelvic lymph nodes (CTV-LN). The organs at risk delineated were the rectum, urinary bladder, small intestine, bulb of the penis, femoral heads bilaterally and PBM. The dose prescribed to the CTV-PSV was 76 Gy in 38 fractions given over 7.5 weeks and the dose to CTV-LN was 54 Gy in 38 fractions given over 7.5 weeks. Planning target volume (PTV) was created from the CTV with a margin of 5 mm in all direction. For assessment of PBM dose, V10, V20, V30, V40, V50 and mean dose were calculated. The dose volume histogram of PTV and PBM for both techniques was compared. \u0000Results: The mean dose of PTV 54 Gy was achieved in both techniques adequately with better sparing of organs at risk with the VAMT technique. The mean dose for PBM in the VMAT technique was significantly less than that in the IMRT (21.7 Gy vs. 25.8 Gy, respectively; p < 0.001). The significant differences in PBM doses were in the range of 20 Gy to 40 Gy. \u0000Conclusion: In radical treatment of prostate cancer, VMAT technique can offer comparable conformality to IMRT with better PBM preservation. Awareness of PBM delineation and reduction of its doses using VMAT can help to decrease the hematological toxicity.","PeriodicalId":33915,"journal":{"name":"Research in Oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45006294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were randomized to receive adjuvant conventional radiotherapy 200 cGy x 25 fractions with 200 cGy x 5 fractions boost to the tumor bed in case of breast conservation (control arm) or hypofractionated radiotherapy 266 cGy x 16 fractions with 266 cGy x 4 fractions boost to the tumor bed in case of breast conservation (intervention arm).

The standard treatment of GCTB was surgery until the approval of denosumab. Aim: To describe the outcome of treatment of this rare tumor and to determine factors that influence survival. Methods: Retrospective review of the medical records of GCTB patients treated at our institution. Collected data includes: clinicopathological data, treatment modalities and possible prognostic factors. Results: Forty-two patients were identified between May 2008 and November 2017. Their median age was 31 years, and the majority (62%) were females. The commonest primary sites were the upper and lower limbs (50% and 43%, respectively). Eight (19%) patients initially presented with lung metastases. Thirteen (31%) patients received denosumab as first line treatment before surgery and 12 of them underwent surgery post-denosumab. Denosumab was given after recurrence in 12 (29%) patients [8 (19%) with lung metastasis and 4 (10%) with localized disease]. The objective response rate to denosumab after recurrence was 50%. Four (10%) patients achieved complete response and 2 (5%) partial response. After a median follow up of 4.7 years, 6 (14%) patients had local recurrence and 8 (19%) had lung metastasis with no recorded deaths. The 5-year progression-free survival rate was 61%.

One of the important drugs that are affected by shortage is leucovorin. It is used with 5-fluorouracil in many protocols for gastro-intestinal tumors and its shortage would have a negative impact on the treatment outcome. Aim: To compare the effect of low-dose leucovorin versus the standard-dose in the treatment of stage II and III colon cancer. Methods: The study included 100 patients with stage II or III adenocarcinoma of the colon who presented to the Clinical Oncology Department at Mansoura University Hospital from January 2011 till December 2012 after curative resection and were scheduled to receive adjuvant FOLFOX6 regimen. Patients were randomly allocated to receive standard-dose leucovorin (200 mg/m2, group 1) or low-dose leucovorin (125 mg/m2, group 2), both administered on days 1 and 2 over 2 hours infusion before 5-fluoruracil. The end points were toxicity, disease free survival (DFS) and overall survival (OS). Results: The two study groups were matched regarding age, sex, and tumor stage. The mean DFS was 48.36 months for group 1 and 49.12 for group 2 with no significant difference (p=0.866). The mean OS was 65.07 months for group 1 and 62.45 for group 2 with no significant difference (p=0.544). Similarly, there was no significant difference between the two groups regarding hematosuppression, diarrhea, mucositis, neurotoxicity and the need for hospitalization.

The majority (70%) of responders were young oncologists and 62% had >10 years experience in the oncology field. Females represented 52% of them and 62% were married. The MBI-HSS scores indicated that 72% of participants had burnout on the emotional exhaustion (EE) scale, 49% on the depersonalization (DP) scale and 38% on the personal accomplishment (PA) scale. A significantly lower PA score was associated with female gender, being single, viewing vacation time as insufficient, and an experience duration <10 years in oncology (p = 0.01, 0.01, 0.03, and 0.02; respectively). The preference not to choose again oncology as a career was also associated with significantly lower PA score and higher EE score (p=0.02 and 0.001; respectively).
