We conducted a retrospective follow-up study to determine if adjunctive radiotherapy (RT) affected disease-free survival in patients with oral squamous cell carcinoma (SCC) who were found to have close surgical margins after tumor resection. Our study population was made up of 110 patients—72 men and 38 women, aged 30 to 94 years (median: 66) at the time of diagnosis. Their follow-up ranged from 12 days to 5.2 years (median: 3.6 yr). Of this group, 40 patients had free margins, 55 patients had close margins, and 15 had involved margins after surgery. Only 31 of these patients received postoperative RT, including 17 who had close margins. We would expect to find better postoperative local tumor control with combined surgery and RT, but we found no statistically significant difference in disease-free survival between the surgery-plus-RT group and the surgery-only group (p = 0.72). We also found no significant difference in disease-free survival between patients with a tumor of the floor of mouth and those with a tumor of the tongue (p = 0.34). In the study population as a whole, the disease-free survival rate was 81.0% and the overall survival rate was 78.2%. Our findings support the trend toward a watch-and-wait approach before initiating postoperative RT for patients with close surgical margins. The decision should be carefully discussed between the surgeon, the oncologic radiotherapist, and the patient.

144 Background: The aim of this study is to evaluate the long-term clinical and oncologic outcome of ESD for differentiated EGC of an expanded indication compared to surgical resection. Methods: Retrospective analyses were performed in patients who underwent ESD or surgical resection for EGC of an expanded indication from 2006 and 2008 in Incheon St. Mary’s Hospital, Seoul St. Mary’s Hospital, Yeouido St. Mary’s Hospital, and St. Paul’s Hospital. First arm study was performed according to pre-ESD diagnosis including pathologic diagnosis and endoscopic findings. Second arm study was obtained from post-ESD final pathologic result. All the patients were checked with endoscopy and stomach CT regularly at least 5 years. Clinical outcomes, disease free survival and overall survival were compared between the ESD group and surgical resection group in each arm. Results: In first arm study, 41 patients who received ESD and 106 patients who received surgical resection were enrolled. Metachronous recur was found in 4 patients among ESD group and in 2 patients among surgical resection group during the follow up period. There was no local recurrence in both groups. The disease free survival was not different between the two groups (ESD vs surgical resection; 87.8 vs 95.3%, p=0.291). The 5-year overall survival rate was 100% in both groups. In second arm study, 74 patients who received ESD and 165 patients who received surgical resection were enrolled. Metachronous recur was found in 5 patients among ESD group and in 2 patients among surgical resection group during the follow up period. Local recurrence did not occur in both groups. Surgical resection group was superior to ESD group in disease free survival (97.6% vs 87.6%, p=0.002). The 5-year overall survival rate was 100% in both groups. Conclusions: ESD for EGC might be acceptable considering the overall survival rates. However, intensive surveillance should be performed to find the metachronous recur after ESD.

e13575 Background: Long-term safety of pregnancy after breast cancer still remained controversial, especially according to tumor subtypes. Prior results of other studies have limitations of short follow-up periods or small groups. Methods: We analyzed a population-based retrospective cohort data extracted from a random sample of 50% of women aged between 20 and 60 years who were diagnosed with breast cancer from 2002 to 2017 in the Korean National Health Insurance Service database. Propensity score matching analysis for age and Charlson Comorbidity Index (CCI) variables was performed for pregnant groups and non-pregnant groups with the same type of hormone therapy, chemotherapy and surgery. Study population was categorized to 4 biologic subgroups by the combination of hormone therapy, chemotherapy and target therapy. In this observational study, 1,566 patients with pregnancy after breast cancer were matched (1:2) to 2,462 non-pregnant patients of similar characteristics, adjusting for guaranteed bias. The matched patients were followed up to 7 years, or disease and mortality occurrence after the diagnosis of breast cancer. Survival estimates were calculated using the Kaplan-Meier analysis, groups were compared with the log-rank test. Results: Mean time from diagnosis to pregnancy was 3.4 years in study population. At a follow-up of 7 years after pregnancy, no inferiority in disease-free survival and overall survival was observed in pregnant patients factoring in treatment bias. In sub-analysis according to tumor subtypes, no difference in disease-free survival was observed between pregnant and non-pregnant patients in HR-positive and triple negative subgroup ( p= 0.088, p= 0.048, respectively). Likewise, no overall survival difference was observed in ER-positive patients and triple negative patients ( p= 0.05∼0.73, p= 0.03∼0.09, respectively). Conclusions: Our observational data provides reassuring evidence on long-term safety of pregnancy in young breast cancer patients, regardless of tumor subtypes.

The use of modular endoprostheses is a viable option to manage both tumor resection and severe bone loss due to nonneoplastic conditions such as fracture sequelae, failed osteoarticular grafts, arthroplasty revisions, and periprosthetic fractures. We sought to investigate both midterm complications and failures occurred in 87 patients who underwent a megaprosthetic reconstruction in a nonneoplastic setting. After a mean follow-up of 58 (1–167) months, overall failure-free survival was 91.5% at 1 year, 80% at 2 years, 71.6% at 5 years, and 69.1% at 5 and 10 years. There was no significant difference in the survival rate according to the diagnosis at the index procedure (p=0.921), nor to the reconstruction site (p=0.402). The use of megaprostheses in a postneoplastic setting did not affect survival rate in comparison with endoprosthetic reconstruction of pure nonneoplastic conditions (p=0.851). Perimegaprosthetic infection was the leading complication, occurring in 10 (11.5%) patients and implying a megaprosthetic revision in all but one case. Physicians should consider these results when discussing with patients desired outcomes of endoprosthetic reconstructions of a nonneoplastic disease.

Breast cancer is the most prevalent female malignancy. When diagnosed at young age (up to 40 years), negative clinical, morphological and prognostic features are noted. A non-randomized retrospective trial (n=500) was performed to evaluate different scenarios of breast cancer hormone therapy in young patients. Ovarian suppression in young patients is shown to statistically improve prognosis. Disease-free survival rate values are observed to decrease in patients without ovarian suppression in comparison with any type of ovarian suppression, especially at a remote follow-up (after 60 months). Menstrual function resumption and no amenorrhea after chemotherapy significantly decrease disease-free survival rate values in young patients.

Abstract Backgroud: Longer follow-up was necessary to testify the exact value of mastoscopic axillary lymph node dissection (MALND).Methods：From January 1, 2003 to December 31, 2005,1027 patients with operable breast cancer were randomly assigned to two groups: MALND and CALND. 996 eligible patients were enrolled. The end points are disease free survival and overall survival.Results：The final cohort of 996 patients was followed for an average of 184 months. The distribution of all events was fairly similar between two groups of patients. The incidence of local in-breast events did not differ in a significant manner between two cohorts. Similarly, the rate of distant metastases was not significantly different with 30.0% in MLND and 32.6% in CALND. And no significant difference was observed in other primary tumor between two groups (p=0.46). Patients who remain alive with no event comprise a total of 37.2% in MALND and 35.4% in CALND. Other primary cancers and deaths from other causes were distributed equally between two groups. The 15-year disease-free survival rates were41.1 percent for the MALND group and 39.6 percent for the CALND group (p=0.79). MALND was found to be not inferior for overall survival (P =0.54). The 15-year overall survival rates were 49.5 percentafter MALND and 51.2 percentafter CALND (p=0.86). Probability of overall survival was not significantly different between two groups.Conclusions：MALND does not increase unfavorable events, and also does not affect the long-term survival of patients. Therefore, MALND should be one of the preferred approaches for breast cancer surgery.

From January 1985, 28 patients affected by locally advanced bladder cancer (pT2-pT4a, pNx-N0-N1-2, MO) underwent 4 planned cycles of adjuvant chemotherapy with cisplatin (70 mg/m2 on day 1) and methotrexate (40 mg/m2 on days 8 and 15) after cystectomy. Gastrointestinal toxicity and agranulocytosis were so severe that only 50% of the patients completed the four planned cycles. After a median follow-up of 36 months (range 9-89 months), the overall 5-year disease-free survival rate of 26 evaluable patients was 32%. None of the patients with pathological evidence of lymph node metastases survived longer than 5 years, while the 5-year disease-free survival rate of the patients without nodal involvement was 55%. Seventy-five percent of progressions (12/16) were identified within 24 months. Only 28% of the patients submitted to salvage chemotherapy with an M-VAC regimen after progression showed a partial response of short duration to chemotherapy.

Due to its rarity, there are no randomized trials investigating the outcome of adjuvant radiotherapy in MBC. This study reports on patient and tumor characteristics of 41 consecutive MBC patients treated between 1990 and 2018 and on clinical outcomes after surgical resection of tumors and adjuvant radiotherapy of the chest wall or breast. Local control (LC), locoregional control (LRC), overall survival (OS), disease-free survival (DFS), and toxicity were evaluated. After a median follow-up of 80 months (95% CI: 14.6–213.8 months) there was only one recurrence, in a patient’s locoregional lymph nodes 17 months after start of radiotherapy, resulting in an LC rate of 100% at 5 years and a 5-year LRC rate of 97.4% (standard deviation (SD): 0.025). Five-year DFS and OS rates were 64.6% (SD: 0.085) and 57.2% (SD: 0.082), respectively. Adjuvant radiotherapy was tolerated well without high-grade (CTCAE grade > II) adverse events. After tumor resection and adjuvant radiotherapy, LC and LRC rates in MBC patients are excellent and comparable to results found for female breast cancer (FBC) patients. However, as patients are often diagnosed with locally advanced, higher-risk tumors, distant recurrences remain the major failure pattern.

In the period 01.01.1991 - 12.31.1996, 523 operations due to rectal carcinoma were performed on the First Surgical Clinic, the Third Department for Colorectal Surgery. Most common localization of tumor was in the distal third of the rectum 65,2%. In the middle third, there were 28,9% and in the upper, intraperitoneal third 5,9%. We performed 286 low anterior stapled resections, 93 anterior resections with hand-sewn anastomosis and 144 Abdominoperineal excisions of rectum (Miles procedure). Pathohistological examination revealed adenocarcinoma in all cases. In this study we analyzed local recurrence and five-year survival after long-term follow-up in the group where Miles procedure was carried out as a potentially curative procedure (except 4,9% cased with Dukes D stage). There were 74,3% males and 23,7% females median age 59,2 years. According to Dukes classification there were 4,9% in stage A, 47,2% in stage B, 43,1% stage C, and 4,9% stage D. There were 4 (2,7%) postoperative deaths. Recurrence of the disease was registered in 44 (30,5%) patients. Local recurrence alone was found in 14 (9,7%) patients, while distant spread was registered in 30 (20,8%) patients. At present, the median follow-up is at 72,9 months. Analysis by the Kaplan-Meier's test shows cumulative survival of 61%, and disease free survival of 63,4% at 60 months of the follow-up. Dukes C is associated with a very poor prognosis; sur-M\al after 60 months of follow up shows cumulative Survival of 0,35 while Dukes B has far better prognosis (0,86). Analysis of disease free survival by Dukes stage shows that Dukes C has the worst prognosis (disease free survival 0,36 after 60 months), while stage B has much better prognosis (0,84). Local recurrence analysis by the Kaplan-Meier's test shows disease free survival of 84,9% at 60 months of follow-up. Analysis of local recurrence by Dukes stage shows 1,00% disease free survival for cases in stage A, 0,94 for Dukes B and 0,66 for Dukes C, while overall comparison between groups regarding local recurrence using the Wilcoxon (Gehan) statistic shows statistically significant difference (p=0,005). There is no statistical difference between Dukes A and Dukes B cases in distribution of local recurrence.

BackgroundSacroiliac joint tumor is rare, and the reconstruction after tumor resection is difficult. We aimed to analyze and compare the clinical effects of three-dimensional (3D) printed prostheses and bone cement combined with screws for bone defect reconstruction after sacroiliac joint tumor resection.MethodsTwelve patients with sacroiliac joint tumors who underwent tumor resection and received 3D-printed prostheses to reconstruct bone defects in our hospital from January 2014 to December 2020 were included in the study group Twelve matched patients who underwent sacroiliac joint tumor resection and reconstruction with bone cement and screws in the same time period were selected as the control group.ResultsIn the 3D-printing group, six cases were extensively excised, and six cases were marginally excised. All patients were followed up for 6–90 months, and the median follow-up time was 21 months. Among them, nine patients had disease-free survival, two survived with tumor recurrence, and one died due to tumor metastasis. The MSTS-93 score of the surviving patients was 24.1 ± 2.8. The operation time was 120.30 ± 14.50 min, and the intraoperative bleeding was 625.50 ± 30.00 ml. In the control group, seven cases were extensively excised, and five cases were marginally excised. All patients were followed up for 6–90 months, with a median follow-up time of 20 months. Among them, nine patients had disease-free survival, one survived with tumor recurrence, and two died due to tumor metastasis. The MSTS-93 score of the patients was 18.9 ± 2.6. The operation time was 165.25 ± 15.00 min, and the intraoperative bleeding was 635.45 ± 32.00 ml. There was no significant difference in survival status, intraoperative blood loss, or complications between the two groups (P>0.05). However, there were statistically significant differences in operative time and postoperative MSTS-93 scores between the two groups (P<0.05).ConclusionsAfter resection of the sacroiliac joint tumor, reconstruction using 3D printed prostheses was shorter and resulted in better movement function.

PURPOSE To compare two adjuvant combination chemotherapies, cyclophosphamide, methotrexate, and fluorouracil (CMF) and chlorambucil, methotrexate, and fluorouracil (LMF), for patients who had undergone potentially curative surgery for unilateral breast cancer, in terms of relapse, survival, and toxicity. PATIENTS AND METHODS Selection criteria was as follows: stage pT1-3a, N+ or N-, M0, less than 72 years of age. Eligible patients were randomized to receive either CMF (cyclophosphamide 100 mg/m2 orally on days 1 to 14, methotrexate 40 mg/m2 intravenously (I.V.) on days 1 and 8, fluorouracil 600 mg/m2 I.V. on days 1 and 8) or LMF (Leukeran [Wellcome A.G., Bern, Switzerland] 5 mg/m2 orally on days 1 to 14 with the some I.V. cytostatic drugs). Follow-up examinations were performed every 3 months during the first 3 years after mastectomy, and every 6 months thereafter. RESULTS A total of 246 patients were randomized, of whom 232 who were fully eligible and contribute to the analyses presented here. No statistically significant difference in favor of adjuvant CMF over LMF emerges after a median follow-up duration of 11.2 years, for either overall survival (P = .15) or disease-free survival (P = .14). A consistent trend suggestive of a possible relative benefit associated with CMF should be pointed out. However, CMF presents a significantly worse toxicity profile as concerns hematologic parameters as well as alopecia, nausea, and vomiting. CONCLUSION This prospective trial has not identified a statistically significant difference in disease-free survival or overall survival between the two adjuvant regimens LMF and CMF. Although a trend in favor of CMF has been observed in premenopausal patients, this has to be weighted against its definitely more pronounced toxicity profile.
