Abstract
PURPOSE Early-onset colorectal cancer (EOCRC) is a rising health problem. The incidence of EOCRC has increased over the past 2 decades all over the world. Reports from Egypt since the 1990s have reported a higher incidence among young populations with no identifiable risk factors. The aim of this study was to assess EOCRC in Egypt regarding incidence, characteristics, treatment pattern, and survival compared with average age onset and elderly patients. MATERIALS AND METHODS This was a retrospective, record-based, cohort study combining data from four different cancer centers in Egypt. We grouped patients according to age into three categories: the EOCRC group for patients age ≤45 years and the average age onset and elderly cancer group (for patients age ≥65 years). RESULTS The study included 1,310 patients with histopathologically proven colorectal cancer, representing four different geographical areas in Egypt. Patients with EOCRC represented 42.4% of the study population. Female patients were 50.6% among the EOCRC group and 52.5% among the average age group. Rectal tumors were significantly higher in EOCRC (54.7% v 40.6%; P < .001). There was no significant difference between both groups regarding the tumor stage at presentation, obstruction, or presence of metastases at presentation. Patients with EOCRC had a significantly higher rate of peritoneum/adnexa metastases than the average age ones (12.3% in EOCRC v 6.9% in the average age group; P < .001). No statistically significant differences between EOCRC and average age groups in both disease-free survival and overall survival were reported. CONCLUSION A comprehensive framework for the study of EOCRC is required in Egypt as well as a genomic analysis to identify possible underlying genetic alterations responsible for the high incidence of EOCRC.

Abstract
Purpose Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide and the second cause of cancer related mortality. Treatment options for patients with metastatic CRC (mCRC) expanded during the last two decades, with introduction of new chemotherapeutic and targeted agents. Egypt is a lower middle-income country; Egyptian health care system is fragmented with wide diversity in drug availability and reimbursement policies across different health care providing facilities. We report the results of consensus recommendations for treatment of patients with metastatic colorectal cancer developed by Egyptian Foundation of Medical Sciences (EFMS), aiming to harmonize clinical practice through structured expert consensus-based recommendations consistent with the national status. EFMS recommendations could be utilized in other countries with similar economic status. Methods EFMS recommendations were developed using a modified Delphi process, with three rounds of voting till the final recommendations were approved. A non-systematic review of literature was conducted before generating the provisional statements. Content experts were asked to vote on some recommendations in two different resource groups (restricted resources and non-restricted resources). External review board of experts from a low income and lower-middle countries voted on the applicability of EFMS recommendations in their countries. Results The current recommendations highlighted the discrepancy in health care between restricted and non-restricted resources with expected survival loss and quality of life deterioration. Access to targeted agents in first line is very limited in governmental institutions, and no access to agents approved for third line in patients who failed oxaliplatin and irinotecan containing regimens for patients treated in restricted resource settings. Conclusion Management of mCRC in developing countries is a challenge. The currently available resource-stratified guidelines developed by international cancer societies represent a valuable decision-making tool, adaptation to national status in each country based on healthcare system status is required.

Abstract
Simple Summary Central neurocytoma is a rare tumor accounting for <0.5% of all intracranial tumors. We analyzed 33 patients treated with surgical resection with or without radiotherapy from ten closely cooperating institutions in Germany, Egypt, and Jordan. Patients who received radiotherapy had longer progression-free survival with an acceptable toxicity profile. Abstract Background: Central neurocytoma (CN) is a rare tumor accounting for <0.5% of all intracranial tumors. Surgery ± radiotherapy is the mainstay treatment. This international multicentric study aims to evaluate the outcomes of CNs patients after multimodal therapies and identify predictive factors. Patients and methods: We retrospectively identified 33 patients with CN treated between 2005 and 2019. Treatment characteristics and outcomes were assessed. Results: All patients with CN underwent surgical resection. Radiotherapy was delivered in 19 patients. The median radiation dose was 54 Gy (range, 50–60 Gy). The median follow-up time was 56 months. The 5-year OS and 5-year PFS were 90% and 76%, respectively. Patients who received radiotherapy had a significantly longer PFS than patients without RT (p = 0.004) and a trend towards longer OS. In addition, complete response after treatments was associated with longer PFS (p = 0.07). Conclusions: Using RT seems to be associated with longer survival rates with an acceptable toxicity profile.

Abstract
Purpose Breast cancer in men accounts for approximately 1% of all breast cancers. Breast cancer trials have routinely excluded men. The aim of this analysis was to determine the effect of different treatment factors, in particular, postoperative radiation therapy (RT) on long-term outcomes. Methods and Materials Seventy-one patients with male breast cancer treated in 5 closely cooperating institutions between 2003 and 2019 were analyzed. Results Almost all patients (95%) underwent surgical resection. Forty-two patients (59%) received chemotherapy, and 59 (83%) received adjuvant hormonal therapy. Of the 71 patients, 52 (73%) were treated with RT. The rate of recurrence was 20% in the whole cohort, with a locoregional recurrence rate of 3%. In the entire group, the 5-year local control (LC) was 95%, whereas 5-year progression-free survival (PFS) and 5-year overall survival (OS) were 62% and 96%, respectively. There was a lower rate of relapses after adjuvant RT (19% vs 32%, P = .05) without in-field relapse after postoperative RT (0%) versus 10% in patients without RT (P = .02). In the multivariate analysis performed, hormonal therapy administration was found to have a possible significant effect on LC and PFS. Administration of adjuvant RT and stage affect PFS. In patients who received RT, there were no grade 3 or 4 acute toxicities. Conclusions Adjuvant RT is an effective and safe treatment for male breast cancer patients with no infield relapses and better PFS. Hormonal therapy administration was found to have a possible effect on LC and PFS.

Abstract
BACKGROUND Regenerative medicine modalities provide promising alternatives to conventional reconstruction techniques but are still deficient after malignant tumor excision or irradiation due to defective vascularization. METHODS We investigated the pattern of bone formation in axially vascularized tissue engineering constructs (AVTECs) after irradiation in a study that mimics the clinical scenario after head and neck cancer. Heterotopic bone generation was induced in a subcutaneously implanted AVTEC in the thigh of six male New Zealand rabbits. The tissue construct was made up of Nanobone (Artoss GmbH; Rostock, Germany) granules mixed with autogenous bone marrow and 80 μL of bone morphogenic protein-2 at a concentration of 1.5 μg/μL. An arteriovenous loop was created microsurgically between the saphenous vessels and implanted in the core of the construct to induce axial vascularization. The constructs were subjected to external beam irradiation on postoperative day 20 with a single dose of 15 Gy. The constructs were removed 20 days after irradiation and subjected to histological and immunohistochemical analysis for vascularization, bone formation, apoptosis, and cellular proliferation. RESULTS The vascularized constructs showed homogenous vascularization and bone formation both in their central and peripheral regions. Although vascularity, proliferation, and apoptosis were similar between central and peripheral regions of the constructs, significantly more bone was formed in the central regions of the constructs. CONCLUSION The study shows for the first time the pattern of bone formation in AVTECs after irradiation using doses comparable to those applied after head and neck cancer. Axial vascularization probably enhances the osteoinductive properties in the central regions of AVTECs after irradiation.

Abstract
Objective. The objective of this study was to explore the effectiveness of date palm pollen (DPP) in the prevention and treatment of oral mucositis induced by radiation and chemotherapy. Methods. Twenty subjects with varying head and neck cancers were enrolled. Ten subjects were treated with DPP administered orally (2 g daily for 42 days) as a swish and swallow suspension, and 10 control subjects received the facility standard of care. Objective oral assessments using the Oral Mucositis Assessment Scale (OMAS) were conducted at baseline and while the subjects were on treatment. Study subjects also evaluated the treatment impact by visual analog scales for severity of mouth pain and ability to swallow. Results. The results obtained demonstrate a statistically significant difference between the mean OMAS score in the DPP treatment group and the control group. Symptoms such as impairment of solid food intake observed with the control group were not observed in the DPP-treated group following the treatment. Reduction of mucositis severity of pain and ability to swallow were statistically significant in the DPP-treated group. Conclusion. DPP treatment reduced the incidence of mouth pain and oral ulcers that often require modifications to soft/liquid diet. The complex mixture of bioactive constituents contained in DPP may have protected the oral mucosa by blocking oxidative free radicals, preventing DNA damage, and neutralizing inflammatory reactions. Further randomized controlled studies are needed to validate DPP efficacy in the broader management of chemotherapy- and radiation-induced mucositis.

Abstract
13531 Background: Preoperative radiotherapy (RT)with or without chemotherapy (CRT) for patients (ptns) with T3,4 rectal carcinoma is increasingly accepted.We presented, 3 yrs ago, our experience with Cisplatin-5FU-Folonic(FA)regimen (FOLFC) in patns with metastatic CR carcinoma.We proved it is comparable to other regimens with lower cost. Methods: Between 10/99 & 8/04, 104 ptns between 18 and 65 year old (PS 0–1) were assessed retrospectively (24 T3 & 80 T4). Ptns received 2 months of ICT Cis(40mg/m2 D1)+FA(200mg/m2 2hrs infusion D1,2)followed by 5FU bolus(400 mg/m2 D1,2)+5FU cont inf(1200 mg/m2 D1–2)this cycle repeated q 2 wks for 8 wks. Starting on wk 9, 5 FU-FA was given as in Mayo-clinic regimen (D1–5, D21–25) with concomitant RT 45Gy in 25 fractions followed by 9 Gy boost to primary tumor. TME was planned at 4–6 wks from completion of ICT. 2 more cycles of FOLFC was given post-operatively. Results: All ptns (104) undergoing CRT completed therapy as planned, with no treatment-related interruptions. No GIII-IV toxicity. The radiological RR (after ICT) was 75% and (4 wks after CRT) was 89% (20CRs, 73PRs). 92% of ptns had subjective R in a median of 24 days from start of ICT in terms of improvement of diarrhea/constipation (90.4%), in obstructive symptoms (40/ 50 ptns)&weight gain in 100% of ptns.Reduced rectal bleeding (100%) & pelvic pain (100%). 17 of 20 ptns who were considered to be inoperable prior to the treatment underwent TME with negative radial margins. Anastomotic leakage occurred in 8 ptns (7.7%). Wound infection occurred in 4 ptns (3.8%). Delayed complications occurred in 3 ptns one required surgery for a stomal stricture. All ptns underwent R0 resection with clear CRM. Pathological CR was found in 32 ptns and in an additional 41 ptns, only microscopic tumor foci were found on surgical specimens. After a median follow-up of 16 months, two ptns had developed LR. Conclusions: ICT followed by synchronous CRT and TME results in marked tumor regression, rapid symptomatic response and achievement of R0 resection. The majority of ptns considered inoperable prior to receiving this treatment underwent successful excision. Given the low toxicity and promising activity, this regimen is being compared to standard synchronous 5FU- pelvic chemoradiation in a randomized study. No significant financial relationships to disclose.
