Clinical analysis of 10 cases with extramedullary plasmacytoma of the head and neck / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the clinical characteristics, treatment methods and outcomes of extramedullary plasmacytoma of the head and neck. Methods: A retrospective analysis was conducted on 10 cases with extramedullary plasmacytoma of the head and neck who were admitted to Henan Tumor Hospital from January 2005 to January 2020. Among the 10 patients, 6 were male and 4 were female. The average age at diagnosis was 56.3 years old (34-74 years old). Among them, 3 cases were located in the nasal cavity, 2 cases in the nasopharynx, 1 case in the sinuses, 2 cases in the larynx, 1 case in the oropharynx, and 1 case in the cervical lymph nodes. Treatments were administered according to tumor size and resection extent. Complete surgical excision (negative margins) was preferred, followed by adjuvant radiotherapy or radiotherapy alone. The clinical characteristics, diagnosis, treatment and prognosis of EMP were analyzed. Results: The patients' symptoms were not specific, frequently with local obstruction symptom and localized masses. All patients were confirmed pathologically as suffering from monoclonal plasmacytoma, with negative bone marrow biopsy and negative skeletal survey. Five patients received surgery, 3 received radiotherapy, and 2 received surgery with additional radiation. The follow-up time was 16-125 months, with a median of 92 months. Two patients developed into multiple myeloma. One patient who received radiotherapy after surgery relapsed after 7 years of follow-up and again received surgical treatment, with no evidence of second recurrence. The remaining patients had no recurrence or progression. Conclusion: Extramedullary plasmacytoma of the head and neck has a good prognosis. Surgical treatment can be considered for completely resectable lesions.

DNA double-strand breaks repair capacity and risk of differentiated thyroid cancer: a case-control study / 中华耳鼻咽喉头颈外科杂志

Objective: To study the influencing factors of DNA double-strand breaks (DSB) repair capacity and relationship with differentiated thyroid cancer (DTC). Methods: A total of 140 patients with thyroid diseases admitted to the Henan Cancer Hospital from January 2020 to March 2020 were retrospectively analyzed, including 26 males and 114 females, aged from 18 to 78 years old. According to the pathological results, the patients were divided into DTC group (90 cases) and control group or benign thyroid nodules (BTN) group (50 cases). The DSB repair ability of peripheral blood T lymphocytes was measured by flow cytometry. The data of two groups were compared by Wilcoxon rank sum test to evaluate the relationship between DSB repair ability and the risk of DTC. According to the median repair ability of DSB in BTN group, the repair ability of DSB was divided into high and low categories, and the factors influencing the repair ability of DSB were analyzed by Logistic regression method. SPSS 22.0 software was used to analyze the data. Results: The DSB repair capacity was 27.87% in DTC group and 36.75% in BTN group, with significant difference (Z=-3.999,P<0.05). Logistic regression analysis suggested that patients with thyroid cancer had lower DSB repair capacity than patients without cancer (OR=2.245; 95%CI: 1.067-4.725; P=0.033), and patients with a history of radiation exposure had a reduced DSB repair capacity (OR=2.698; 95%CI: 1.271-5.725, P=0.010). Conclusion: The risk of DTC increases in patients with low DSB repair capacity. Radiation exposure is a risk factor for the reduction of DSB repair capacity.

Incidence and mortality of oral cavity and pharyngeal cancer in China, 2009 / 中华预防医学杂志

<p><b>OBJECTIVE</b>To analyze the incidence and mortality of oral cavity and pharyngeal cancer in cancer-registration areas of China in 2009.</p><p><b>METHODS</b>We collected data about incidence of oral cavity and pharyngeal from 72 cancer registry sites of National Central Registry Database in 2009, covering 85 470 522 person (57 489 009 were from urban areas, 27 981 513 were from rural areas).Incidence and mortality rates, proportions, cumulative rate (0-74 years old), cut rate (35-64 years old), age-specific rate were then calculated and analyzed respectively. The age-standardized rate was calculated and adjusted by the Chinese standard population in 1982 as well as the Segi's world standard population.</p><p><b>RESULTS</b>There were 2803 new diagnosed oral cavity and pharyngeal cancer cases, 1793 male and 1010 female, with the sex ratio at 1.78: 1. The crude incidence rate of oral cavity and pharyngeal cancer was 3.28/100 000(2803/85 470 522). The crude incidence rate of males was 4.15/100 000(1793/43 231 554) while it was 2.39/100 000(1010/42 238 968) among females. The age-standardized incidence rates by Chinese standard population (ASIRC) and the world standard population were 1.72/100 000 and 2.23/100 000 respectively, and the cumulative rate and cut rate was separately 0.26% and 4.02/100 000. The crude incidence and ASIRC of oral cavity and pharyngeal cancers were 3.87/100 000 (2225/57 489 009) and 1.97/100 000 in urban areas, whereas in rural areas, they were 2.07/100 000(578/27 981 513) and 1.17/100 000. There were 1172 death cases, including 825 males and 347 females. The crude mortality rate was 1.37/100 000 (1172/85 470 522), while it was 1.91/100 000(825/43 231 554) among males and 0.82/100 000(347/42 238 968) among females. The age-standardized incidence rates were 0.64/100 000 and 0.88/100 000 respectively, by Chinese standard population (ASMRC) and the world standard population. The cumulative mortality rate (0-74 age years old) and cut rate were separately 0.10% and 1.34/100 000. The mortality and ASMRC were 1.59/100 000(915/57 489 009) and 0.72/100 000 in urban areas, whereas in rural areas, they were 0.92/100 000(257/27 981 513) and 0.48/100 000 respectively.</p><p><b>CONCLUSIONS</b>Both the incidence and mortality of oral cavity and pharyngeal cancer in China were still low in 2009.</p>

Rehabilitation evaluation of Amatsu's tracheoesophageal shunt operation after total laryngectomy with sphincter mechanism / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To evaluate rehabilitation effect of Amatsu's tracheoesophageal shunt operation after total laryngectomy with sphincter mechanism.</p><p><b>METHODS</b>Voice rehabilitation were performed for 60 cases with Amatsu's tracheoesophageal shunt operation after total laryngectomy with sphincter mechanism, in which 20 cases were involved in post-operation radiation therapy.</p><p><b>RESULTS</b>Fifty two (86.7%)cases developed speech with voice and swallow rehabilitation, but 1 case of them suffered water drip from his tracheoesophageal shunt when drinking. The other 8 (11.3%) cases developed swallow rehabilitation but failed in speech rehabilitation for pharyngeal fistula (4 cases, in which 1 had pre-operative radiation therapy), tracheoesophageal shunt obstruction (2 cases), dyspnea with unknown reason (1 cases), no desire to speech (1 cases). Furthermore, all the 20 cases who were involved in post-operative radiative therapy restore their speech and swallow capability finally.</p><p><b>CONCLUSIONS</b>Amatsu's tracheoesophageal shunt operation with sphincter mechanism brought effective speech rehabilitation results for total laryngectomy even with post-operation radiation therapy.</p>
