Research progress of intravesical recurrence after radical resection of upper tract urothelial carcinoma / 现代泌尿外科杂志

Urothelial carcinoma (UC) is the second most common genitourinary tumor, and upper tract urothelial carcinoma (UTUC) accounts for 5% to 10% of UC. Intravesical recurrence (IVR) occurs in 22% to 47% of patients after radical resection. This article reviews the mechanism, characteristics, related risk factors, regular bladder monitoring, diagnosis and treatment, and preventive measures of IVR, hoping to provide reference for clinical work.

Clinical characteristics and efficacy of oropharyngeal carcinoma with secondary primary tumor / 临床耳鼻咽喉头颈外科杂志

Objective:To analysis the clinical features and prognosis in oropharyngeal carcinoma with secondary primary tumor. Methods:A retrospective analysis was performed on 468 pathologically confirmed oropharyngeal cancer as the primary tumor patients with p16 status, excluded distant metastasis, and admitted to the Chinese Academy of Medical Sciences from January 2010 to December 2020. The clinical features and prognosis of the secondary primary tumor were analyzed. Results:Among 468 patients with oropharyngeal cancer treated at initial diagnosed, 222 cases were P16-negative. With a median follow-up time of 64.3 months, 66 cases developed second primary cancer, with an incidence of 29.3%, among which 63.6%（42/66） were synchronous and 36.4%（24/66） were heterochronous, esophagus was the most commonly involved site. The 5-year OS of p16-negative oropharyngeal carcinoma with synchronous second primary cancer, without second primary cancer and with heterogeneous second primary cancer were 26.3% and 57.3% and 73.2%（P=0.001）; The second primary cancer accounted for 11.2%（12/107） of the deaths in the whole group, among them, the heterochronous second primary accounted for 75.0%（9/12）. There were 246 patients with p16 positive, with a median follow-up time of 52.4 months, 20 patients developed second primary cancer（8.1%）. Among them, 65.0%（13/20） were synchronous and 35.0%（7/20） were heterochronous. Esophagus was the most commonly involved site. The 4-year OS of p16-positive with synchronous, heterochronous and non-second primary cancer group were 51.9%, 80.7% and 83.3%. Secondary primary cancer accounted for 3.8%（2/52） of all deaths in p16 positvie group. Conclusion:The incidence of second primary cancer of p16 positive and negative oropharyngeal carcinoma were different. The esophagus was the most commonly involved site regardless of p16 status. Regardless of p16 status, the survival of patients with synchronous second primary cancer was worse than those without second primary cancer. For p16-negative oropharyngeal carcinoma, the prognosis was better in patients with heterogeneous second primary cancer, the second primary cancer is one of the main causes of death.

Experience of YU Yun in Treating Primary Carcinoma of Liver by Using Acupuncture after Pulse Diagnosis / 中国中医药信息杂志

This article introduced the experience of Professor YU Yun in treating the primary carcinoma of liver by using acupuncture after pulse diagnosis. Professor YU thinks that the overall pathogenesis of liver cancer is deficiency of zang-fu organs, so the cancer cells can invade and occupy in the liver. Therefore, Professor YU uses the way of supporting the healthy qi and driving out the cancer as the treatment principle from multiple organs and meridians. On the basis of the theories of Nei Jing, Professor YU creates the acupuncture after pulse diagnosis. He feels the pulse on the basis of four pulses: Cunkou, Renying, Chongyang, and Taixi. According to the feelings of the pulses, he compares the size and speed, strong or weak, smooth or nonfluency of the four pulses. In treatment, he uses reducing method when the pulse is strong and fast, and tonic method when the pulse is weak and slow. He chooses the main acupuncture points on head, face, belly, flank and lower limbs. According to the experience, Professor YU uses gold needle in tonic method and uses silver needle in reducing method. In this way, the acupuncture after pulse diagnosis can regulate zang-fu organs and meridians, yin and yang, qi and blood, and promote blood circulation for removing blood stasis and resolving dampness, and attack the retained fluid and tumour in the liver, and combined with adjunct points to treat cancer.

Application of 18F-FDG PET/CT in patients with synchronous multiple primary carcinoma / 肿瘤

Objective: To investigate the value of 18F-fluorodeoxyglucose (18F-FDG) PET/CT in detection of synchronous multiple primary carcinoma (MPC) before treatment. Methods: The pre-treatment whole body PET/CT images of seventy-two patients with synchronous MPC confirmed by postoperative and biopsy pathology were analyzed. The pathological results were used as gold standard, and the detection rates of tumor lesions by 18F-FDG PET/CT and plain CT were compared, and the metabolism of 18F-FDG in tumor lesion was analyzed. Results: There were 151 lesions confirmed by pathology in 72 patients with synchronous MPC. The detection rate of tumor lesions by 18F-FDG-PET/CT was 88.1% (133/151), which was significantly higher than that of integrated CT (78.8%, 119/151) (P < 0.05). In patients with first primary cancer in digestive tract and second primary cancer in lung, the maximal standardized uptake value (SUVmax) of first primary cancer in digestive tract was higher than that of second primary cancer in lung (P = 0.042). There was no significant difference in SUVmax between synchronous MPCs in digestive tract (P = 0.345), but there was significant difference in SUVmax between synchronous MPCs in lung (P = 0.046). There were differences in SUVmax among tumor tissue lesions (P < 0.001), and the SUVmax of digestive tract cancer was higher than that of lung cancer (P = 0.01). Conclusion: The whole body18F-FDG PET/CT imaging can effectively detect and diagnose the synchronous MPC.

The 3-year survival rate was 20.8％ and the 5-year survival rate was 8.3％.Conclusions Regular B-ultrasonography,CT-scan and MRI are suggested for elderly patients with chronic diseases of the gallbladder.Radical resection is recommended if clinically possible. Chinese traditional medicine given postoperatively improved the prognosis.

Detection of helicobacter species related genes in mucosa and bile in the primary carcinoma of the gallbladder / 中华肝胆外科杂志

Objective To investigate the relationship between helicobacter pylor (Hp) and primary carcinoma of the gallbladder (PCG), providing a theoretical basis for the treatment of PCG.Methods Mucosa and bile of gallbladder samples were collected from 18 patients with PCG (PCG group), 40 patients with chronic cholecystitis or cholelithiasis (CC group), and 20 patients with no PCG and CC (control group). 16S rDNA-based polymerase chain reaction (PCR) followed by DNA sequence analysis of the obtained PCR fragments was performed. A developed search for Hp was also carried out by PCR. Five genes specific for Hp were amplified. Results In the PCG group, 81% samples of mucosa and bile were positive for Helicobacter-specific 16S rRNA gene. The positive rate in PCG group was significantly higher than those of the CC group (50%) and the control group (20%).Of the 16S rDNA sequence of Helicobacter pylori positive samples of mucosa and bile, 52% of samples were positive in cagA, 86% were positive in 26 KDa, 48% were positive in ureA separately. The vacA and rps4 genes were never detected in any of the samples of mucosa and bile. At least one gene was positive in 93% of samples of musca and bile. The sequencing showed more than 99% homology of Helicobacter 16S rRNA in PCG and Hp groups. Conclusion A higher infection rate is present in bile and gallbladder mucosa from patients with PCG. Hp in the biliary system may be one of the risk factors for occurrence of PCG.

The expression of CDH1 gene methylation in patients with esophagus and stomach double primary carcinoma and its significance / 中华消化杂志

Objective To study the changes of CDH1 gene promoter CpG island methylation and its clinical significance in patients with esophagus and stomach double primary carcinoma(ESDC).Methods The expression of CDH1 gene methylation in cancerous tissues and adjacent cancerous tissues in 18 cases of ESDC were detected using methylation-specific PCR method. Results Eighteen patients were endoscopically diagnosed as ESDC between Jan. 2007 and Sep. 2009 in the 4th Hospital Affiliated to Hebei Medical University. The positive methylation of CDH1 gene in tissues of esophageal squamous cell carcinoma (ESCC)and adjacent cancer were 66.7% and 33. 3%, respectively, with significant difference (χ2= 4. 167, P = 0. 031). Whereas the positive methylation of CDH1 gene in tissues of gastric carcinoma (GA) and adjacent cancer were 77.8% and 44.4%, respectively, without statistical difference (χ2=1.786, P= 0. 180). There was no significant difference (P=0. 500) in positive rate of CDH1 gene methylation between ESCC tissues and GA tissues in same individual with ESDC. For 18 patients with ESDC, consistent change of CDH1 methylation in tissues of two kinds of cancers was found in 16 patients with a total agreement of 88.9 % (positive agreement of 66.7 % and negative agreement of 22. 2%). Statistical analysis showed a significant correlation between two groups (P = 0. 005). Conclusion In patients with ESDC, there is a high consistency of CDH1 methylation change, between ESCC and GA,which suggests that two kinds of cancer may have similar risk factors and molecular mechanisms.

Clinicopathological features of multiple primary colorectal carcinoma / 中华消化外科杂志

Objective To investigate the clinicopathological features of multiple primary colorectal carcinoma. Methods The clinical data of 30 patients with multiple primary colorectal carcinoma and 580 patients with single colorectal carcinoma who were admitted to the Peking University People's Hospital from January 2001 to March 2008 were retrospectively analyzed. There were 16 patients with multiple synchronous carcinoma and 14with multiple metachronous carcinoma. The survival of the patients was analyzed using Kaplan-Meier method and the survival rates were compared using Log-rank test. All data were analyzed using the chi-square test. Results The onset age of multiple metachronous primary carcinoma was younger than that of multiple synchronous carcinoma and single colorectal carcinoma, while the onset age of multiple metachronous secondary carcinoma was close to that of multiple synchronous carcinoma and single colorectal carcinoma. Most of the synchronous carcinoma located at the left colon; while most of the metachronous primary carcinoma located at the rectum and sigmoid colon, and most of the metachronous secondary carcinoma located at the ascending colon. Patients with multiple synchronous carcinoma or multiple metachronous primary carcinoma received radical resection. Of the 14 patients with multiple metachronous carcinoma, 9 received radical resection for secondary focus. Except for three patients with multiple synchronous carcinoma and two patients with multiple metachronous carcinoma, all patients received postoperative chemotherapy with FCF, FOLFOX or XELOX regimen. Of the 580 patients with single colorectal carcinoma, 512 received radical resection, 68 received palliative operation, and 519 received postoperative chemotherapy. The cumulative survival rate of patients with multiple metachronous primary carcinoma was significantly higher than that of single colorectal carcinoma (x2 = 17. 289, P ＜ 0. 05). There was no significant difference in the cumulative survival rate between patients with single colorectal carcinoma and those with multiple metachronous secondary carcinoma or multiple synchronous carcinoma (x2 = 1.731, 0. 800, P ＞ 0. 05). Conclusion The prognosis of patients with colorectal multiple metachronous carcinoma is better than those with single colorectal carcinoma, and the prognosis of colorectal synchronous carcinoma is similar to those with single colorectal carcinoma.
