Abstract Background Recently, endoscopic submucosal dissection (ESD) has been used as a less invasive treatment for superficial esophageal cancer. Additional treatment is often required after non-curative resection to prevent local recurrence and lymph node metastasis. Here, we present the outcomes of various additional treatments for patients with superficial esophageal cancer who underwent ESD. Methods Between 2006 and 2017, we performed ESD in 179 patients (210 lesions) with superficial esophageal cancer and 44 cases resulted in the non-curative resection diagnosed by the pathological examination. Among them, 29 patients received additional treatment, whereas 15 patients with no additional treatment were followed up. Additional treatment included esophagectomy (8 patients), chemoradiotherapy (15 patients), ablation using argon plasma coagulation (4 patients), and chemotherapy alone (2 patients). We examined the clinicopathological characteristics and prognosis of patients in the additional esophagectomy group (S group) and chemoradiotherapy group (CRT group). Results Twenty-three patients with pT1a-MM, pT1b, lymphatic invasion, venous invasion, and positive resection margins (both horizontal and vertical) were divided into two treatment groups. Clinicopathological characteristics of patients in the S and CRT groups were not significantly different. Pathological findings after additional esophagectomy showed one residual tumor and one lymph node metastasis. There were no recurrences in the two groups. There was no statistically significant difference in the 5-year overall survival rate between the S group (87.5%) and the CRT group (93.3%). One patient from the S group died due to respiratory pneumonia, and one patient died due to radiation pneumonia. However, five out of the 15 (33.3%) patients who were followed up with no additional treatment developed recurrence. The 5-year overall survival rate was 40.4%, which was not significantly different from that in the additional treatment group. However, the 5-year relapse-free survival rate (30%) was significantly different from that in the additional treatment group (P > 0.05). Conclusion Additional treatment is essential after non-curative endoscopic submucosal resection for esophageal cancer. Additional esophagectomy and chemoradiotherapy were both safe and effective in this cohort. Disclosure All authors have declared no conflicts of interest.

C-Src activity is regulated by tyrosine phosphorylation at two distinct sites, Tyr416 and Tyr527, with opposite effects. However, the clinical roles of these sites in human cancers are not well defined. This study aims to determine whether the alterations and crosstalk of these two sites may contribute to hepatocellular carcinoma (HCC). Specimens from 85 patients who had undergone curative hepatectomy were collected for this study. The patterns of p-Tyr416-Src and p-Tyr527-Src, as well as the non-phosphorylated status for each site, were determined using immunohistochemistry and statistically correlated with clinicopathological characteristics and overall survival rate. The active state of c-Src, p-Tyr416-c-Src, was positively correlated with tumour grade (P= 0.062) but inversely correlated with vascular invasion (P= 0.071). Its non-phosphorylated status, non-p-Tyr416-c-Src, was positively correlated with tumour stage and grade (P= 0.041 and 0.020). The inactive state of c-Src, p-Tyr527-c-Src, was decreased in male patients but increased HCV-infected patients (P= 0.044 and 0.033). The Kaplan-Meier survival curve further showed that increased p-Tyr416-c-Src and decreased non-p-Tyr527-c-Src expression were associated with a poor patient survival rate (P= 0.004 and 0.025). Interestingly, the expression of non-p-Tyr416-c-Src was positively correlated with that of p-Tyr527-c-Src in the HCC lesions (P= 0.040). In addition, the patients with concomitantly low p-Tyr416-c-Src and non-p-Tyr527-c-Src expression had a prolonged overall survival rate (P= 0.030). A multivariable COX regression model showed that p-Tyr416-c-Src expression was an effective predictor for patient survival in HCC [OR = 3.78, 95%CI = 1.46–9.76;P= 0.006]. Our results suggest that the active state of c-Src, p-Tyr416-c-Src, may serve as an independent prognostic marker of patient survival in HCC. Relative levels of other phosphorylated or non-phosphorylated c-Src kinases may also present different statuses during HCC development and require further investigation.

448 Background: We retrospectively assessed the benefits of 5-fluorouracil (5-FU)- and heparin-based portal infusion chemotherapy (PI) combined with systemic administration of mitomycin C (MMC) and cisplatin (CDDP) for 4 weeks following surgery (PI4W). The goal was to determine if this treatment prevented liver metastasis and improved survival for patients with potentially curative resection of pancreatic cancer. Methods: 263 patients who underwent pancreatectomy from January 1985 to December 2013 were treated. Of these cases, 50 patients received portal infusion with 5-FU (250 mg/day) for 2 weeks (PI2W) following surgery (1985 `2001 Group A), while 94 patients received PI4W therapy (250 mg/day of 5-FU with 2,000 IU/day of heparin for 4 weeks, 4 mg MMC on days 6, 13, 20, 27, and 10 mg CDDP on days 7, 14, 21, 28)(2001 `2013 Group B). The remaining 119 patients (Ct) without adjuvant therapy during the perioperative period divided Group A (n=58) and Group B (n=61). Results: The cumulative overall survival rate in the PI2W was significantly higher than those in Ct of Group A. The cumulative overall survival rate in the PI4W also was significantly higher than those in Ct of Group B. Furthermore, in the PI4W group, the rate of liver metastasis is lower than Ct. Conclusions: PI therapy after surgery, especially PI4W, could become a promising adjuvant therapy in patients with potentially curative resection of pancreatic cancer.

Mounting evidence suggests a causal relationship between specific bacterial infections and the development of certain malignancies. In this study, we examined the presence of Porphyromonas gingivalis (P. gingivalis) in oral-digestive tract tumors by immunohistochemistry (IHC) and PCR and analyzed the correlation between P. gingivalis detection and clinicopathological characteristics and prognosis of oral and esophageal carcinoma. The IHC results showed that the positive rates of P. gingivalis were 60.00, 46.00, 20.00, 6.67, and 2.86% in oral, esophagus, cardiac, stomach, and colorectal cancer tissues, respectively. Likewise, PCR results showed rates of 56.00, 42.00, 16.67, 3.33, and 2.86%, respectively. The two methods were consistent, and the kappa value was 0.806, P < 0.001. In addition, P. gingivalis expression was significantly correlated with lymph node metastasis and the clinical stages of oral and esophageal cancer (P < 0.05). The overall survival rate of the P. gingivalis undetected group (86, 50%) was significantly higher than that of the P. gingivalis detected group (57, 14%) for oral and esophageal cancer, respectively. In conclusion, the detection rate of P. gingivalis showed a decreasing trend in oral-digestive tract tumors. Detection with P. gingivalis was associated with poor prognosis for oral and esophageal cancer.

Abstract Background: Ovarian cancer (OC) is one lethal gynecologic cancer, with a 5-year survival rate approximately 47% and localized stage diagnosis of 15%. Circular RNAs are promising biomarkers for malignancies. Methods: CiRS-7 expression was confirmed in 40 paired OC and normal adjacent tissues from 40 OC patients with different TNM stages, lymph node metastasis status and overall survival rate, also 5 different OC cell lines by qRT-PCR. Effects of ciRS-7 silence on OC cell phenotypes were determined in OC cells and Xenograft mouse model. StarBase was used to predict binding sites between ciRS-7 and micRNAs. Pearson correlation analysis and RNA-immunoprecipitation assay were used to determine the association between genes. Point mutation and rescue experiments were applied for molecular mechanism investigation. Results: CiRS-7 expression was significantly higher in OC cells and tissues, which was significantly associated with the TNM stages, lymph node metastasis status and overall survival rate in OC patients. CiRS-7 silence inhibited OC cell growth and metastasis. CiRS-7 sponged miR-641 to up-regulate ZEB1 and MDM2 expression in OC development. Conclusion: CiRS-7 serves as a competing endogenous RNA of miR-641 that promoted cell growth and metastasis in OC, via regulating ZEB1 and MDM2-mediated EMT. High ciRS-7 expression was a poor prognosis of TNM stages, lymph node metastasis status and overall survival rate in OC patients. Targeting ciRS-7/miR-641/ZEB1 or ciRS-7/miR-641/MDM2 axis may be a novel diagnostic, prognostic and therapeutic strategy for OC.

Background: Treatment options for advanced gastric esophageal cancer are quite limited. Chemotherapy is unavoidable at certain stages, and research on targeted therapies has mostly failed. The advent of immunotherapy has brought hope for the treatment of advanced gastric esophageal cancer. The aim of the study was to analyze the safety of anti-PD-1/PD-L1 immunotherapy and the long-term survival of patients who were diagnosed as gastric esophageal cancer and received anti-PD-1/PD-L1 immunotherapy. Method: Studies on anti-PD-1/PD-L1 immunotherapy of advanced gastric esophageal cancer published before February 1, 2020 were searched online. The survival (e.g. 6-month overall survival, 12-month overall survival (OS), progression-free survival (PFS), objective response rates (ORR)) and adverse effects of immunotherapy were compared to that of control therapy (physician’s choice of therapy). Results: After screening 185 studies, 4 comparative cohort studies which reported the long-term survival of patients receiving immunotherapy were included. Compared to control group, the 12-month survival (OR = 1.67, 95% CI: 1.31 to 2.12, P < 0.0001) and 18-month survival (OR = 1.98, 95% CI: 1.39 to 2.81, P = 0.0001) were significantly longer in immunotherapy group. The 3-month survival rate (OR = 1.05, 95% CI: 0.36 to 3.06, P = 0.92) and 18-month survival rate (OR = 1.44, 95% CI: 0.98 to 2.12, P = 0.07) were not significantly different between immunotherapy group and control group. The ORR were not significantly different between immunotherapy group and control group (OR = 1.54, 95% CI: 0.65 to 3.66, P = 0.01). Meta-analysis pointed out that in the PD-L1 CPS ≥10 sub group population, the immunotherapy could obviously benefit the patients in tumor response rates (OR = 3.80, 95% CI: 1.89 to 7.61, P = 0.0002). Conclusion: For the treatment of advanced gastric esophageal cancer, the therapeutic efficacy of anti-PD-1/PD-L1 immunotherapy was superior to that of chemotherapy or palliative care.

The clinical results after carbon ion radiotherapy for the metastatic lung tumors believed to be in the state of oligo-recurrence were evaluated. One hundred and sixteen lesions in 91 patients with lung cancer metastasis were treated with carbon ion radiotherapy at our institute from April 1997 to February 2011. Regarding the prescribed dose, total dose ranged between 40 gray equivalents (GyE) and 80 GyE, and fraction size ranged from 1 to 16 fractions. After a median followup period of 2.3 years (range, 0.3–13.1 years), the statistical overall survival rate and local control rate were 71.2% and 91.9% at 2 years after treatment, respectively. Treatment-related side effects were not a clinical problem. When classified by the primary organ, there were 49 cases of lung cancer, 20 cases of colorectal cancer, and 22 cases of others. The overall survival rate and local control rate for lung metastasis cases from lung cancer at 2 years after treatment were 81.5% and 92.4%, respectively, and 65.0% and 92.0% regarding lung metastasis from colorectal cancer. Carbon ion beam therapy for the metastatic lung tumors is a safe therapy, and the therapeutic effect is comparable to the outcome obtained from reported surgical resections.

Actual Survival

The generally accepted staging for chronic lymphocytic leukemia (CLL) suggested by K. Rai and J. Binet allows calculating the median survival depending on the size of the tumor mass. However, in real clinical practice, the overall survival rate may differ significantly from the calculated median. Thus, the search for parameters affecting the overall survival rate of CLL patients is really relevant. The aim of the study was to assess general clinical parameters as predictors of survival in CLL patients. Materials and Methods. The authors examined 60 CLL men (stages A–C according to Binet) with known overall survival rate. Data mining was used to identify significant factors affecting the overall survival in such patients. Patients were divided into two non-overlapping classes: K1 (actual survival was less than the predicted median survival) and K2 (actual survival was more or equal to the predicted median survival). Results. The most significant differences between the classes were obtained for glomerular filtration rate. If the parameter value is more than 76.5 ml/min/1.73 m2, we can say that the patient will overcome the median survival for the corresponding CLL stage according to Binet. Otherwise, the overall survival of a CLL patient will be less than the estimated one. Conclusion. If during diagnosing glomerular filtration rate of a CLL patient is more than 76.5 ml/min/1.73 m2, it can be considered as a predictor of overcoming the median survival according to Binet. The results of the studies obtained are patented. Patent RU 2725877 C1, July 7, 2020. Keywords: overall survival in CLL patients, men, glomerular filtration rate, data mining. Общепризнанные системы стадирования хронического лимфолейкоза (ХЛЛ) К. Rai и J. Binet позволяют рассчитать медиану выживаемости пациента в зависимости от величины опухолевой массы. Однако в реальной клинической практике параметр общей выживаемости пациента может значимо отличаться от расчетной медианы. Ввиду этого поиск параметров, влияющих на показатель общей выживаемости пациентов с ХЛЛ, представляет особую актуальность. Цель исследования – оценить возможность использования общеклинических параметров в качестве предикторов выживаемости больных ХЛЛ. Материалы и методы. Ретроспективно проанализированы данные 60 мужчин с ХЛЛ стадии A–C по Binet c известной общей выживаемостью. Для выявления значимых факторов, влияющих на общую выживаемость пациентов, использовали метод интеллектуального анализа данных. Пациенты были разделены на два непересекающихся класса: K1 (фактическая выживаемость меньше прогнозируемой медианы выживаемости) и K2 (фактическая выживаемость больше или равна прогнозируемой медиане выживаемости). Результаты. Наиболее значимые различия между классами были получены по показателю скорости клубочковой фильтрации. При значении параметра более 76,5 мл/мин/1,73 м2 можно говорить о том, что пациент преодолеет расчетные данные медианы выживаемости для соответствующей стадии ХЛЛ по Binet. В противном случае общая выживаемость пациента ХЛЛ будет меньше расчетной. Выводы. Наличие у пациента с ХЛЛ на момент постановки диагноза скорости клубочковой фильтрации более 76,5 мл/мин/1,73 м2 можно рассматривать в качестве предиктора преодоления расчетного параметра медианы выживаемости по Binet.

Forty-eight untreated patients with early supraglottic carcinoma (12 patients stage I and 36 patients stage II) had primary carbon dioxide laser microsurgery between 1979 and 1994 with the intent of complete tumor removal with preservation of functionally important structures of the larynx. Ninety-six percent of the patients were treated exclusively by surgery; 4% had laser microsurgery and postoperative radiotherapy. With a median follow-up of 55 months, the 5-year local control rate with the first treatment was 100% for pT1 cases and 89% for pT2 cases. The ultimate local control rate with voice preservation, including patients successfully salvaged after a local recurrence, was 97% for pT2 carcinomas. Five (10%) patients died of tumor (TNM)–related deaths. The 3-year recurrence-free rate and 3-year overall survival rate (Kaplan-Meier) were 87% and 85%; the 5-year recurrence-free rate and 5-year overall survival rate were 83% and 76%, respectively. The results achieved with transoral laser microsurgery in early supraglottic carcinoma are comparable to those of open supraglottic laryngectomy with respect to local control and survival. The functional results are superior, since clinically relevant aspiration did not occur.

BACKGROUND Single modality treatment for stage I and stage II squamous cell carcinomas of glottis region gave excellent results. Since a long time these are treated either with definitive radiation therapy or surgical excision with endoscopes. There was not much difference with regard to voice preservation, local recurrence and disease-free survival period. Our aim was to study the clinical presentation and management protocol of glottis carcinoma in a tertiary hospital and observe the final outcome of stage II (T2N0M0) glottis carcinoma and specific factor for survival in patients treated with surgery, radiotherapy and concurrent chemoradiation. METHODS 43 patients of glottis carcinoma stage II (T2N0M0) attending a tertiary teaching hospital between May 2015 and April 2017 were included in the study. Demography and smoking status of subjects were recorded. Staging of the disease was according to American Joint Committee on Cancer (AJCC) Staging System 7th edition. Paraglottic space infiltration was taken as a criteria to upgrade the staging. The overall survival rate, recurrence free survival, disease specific survival rate and laryngeal function preservation rate were calculated. RESULTS Out of 43 patients, males were 90.69 % and 09.30 % were females. Male to female ratio was 10.57 : 1. Mean age was 58.62 ± 2.35 years. 67.44 % were current smokers, 27.90 % were former smokers and 02.32 % were non-smokers. The overall survival scores and disease specific survival was 100 % with 11.62 % locoregional recurrences. The voice preservation was 86.04 %. Radiotherapy was used in 72.09 %, chemoradiation in 18.60 % patients and 11.62 % patients underwent surgery. 11.62 % patients presented with locoregional recurrence during 24 months of follow up. 02.32 % patients had to undergo tracheostomy. CONCLUSIONS The overall survival scores and disease specific survival were 100 % with 11.62 % loco-regional recurrence. Voice preservation was 86.04 %. Proactive prevention rather than escalation of treatment protocol gives better prognosis.
