ObjectiveGiven the relatively limited resources available for tumor radiotherapy, the reengineering theory to the tumor radiotherapy process of a tertiary hospital is applied to improve the efficiency of medical service, shorten patient waiting time and improve patient satisfaction. MethodsThe tumor radiotherapy process of a tertiary hospital was studied from January 2017 to September 2018. The indicators such as efficiency and satisfaction were analyzed before reconstruction (from January to December 2017) and after reconstruction (from January to September 2018). ResultsAfter radiotherapy process reengineering, on the one hand, the medical efficiency was improved: the number of new patients for radiotherapy per month rose by 16.58% (P<0.05), and the number of daily radiotherapy increased by 5.80% (P<0.05). On the other hand, the patient treatment process became more concise: the preparation time was shortened from 2-3 days to 1 day, while the waiting time for radiotherapy was shortened by nearly 10 days, and the overall satisfaction of patients increased from 64.17% to 83.55%. ConclusionIt can improve the operation efficiency of tumor radiotherapy and improve patient satisfaction under the condition of relatively fixed resources through the reconstruction of the information-based tumor radiotherapy process.
Objective To study the curative effects of keloid by operation combined with postoperative β radiation and silicone gel sheeting. Methods From 1996 to 2002, 598 patients with keloid(243 males, 355 females, aging 15-55 years with an average of 28.6 years) were treated by integrated therapy. Their disease courses were from 6 months to 6 years. The keloid area ranged from 1.0 cm×1.5 cm~8.0 cm×15 cm. First, keloid was removed by operation, and then the wounds weresutured directly(group suture) or covered with skin graft(group graft). In groupsuture, the operational sites were managed by β ray radiotherapy 24-48 hours after operation. The total doses of radiation were 12-15 Gy, 5 times 1 week(group suture A) and 10 times 2 weeks (group suture B). Radiotherapy was not taken until stitches were taken out in group graft, and then the same methods were adopted as group suture B. After radiotherapy, silicone gel sheeting was used in 325 cases for 3-6 months. Results All patients were followed up for 12-18 months. (1) The overall efficacy was 91.3% in group suture A(n=196), and 95.8% in group suture B (n=383), respectively. There was significant difference between the two groups(Plt;0.01). (2) Radiotherapy was of no effect in 6 cases of group graft(n=19). (3) Silicone gel sheeting had effectivenessin 185 cases. Silicone gel sheeting had no obvious effect on the overall efficacy, but it could improve the quality of texture and color of skin. Conclusion By use of integrated methods to treat keloid, if the wound can be sutured directly, skin grafting should not be adopted. The results in group suture B are better than those in group suture A; silicone gel sheeting should be used as possible.
Objective To find individualized evidence-based treatments for a patient with lower rectal cancer. Methods Based on the clinical questions raised, evidence was collected and critically assessed. Patient preferences and physician clinical experience were also taken into consideration in the decision-making treatment. Results Twenty-four systematic reviews or meta analyses and 1 clinical guideline were included. The evidence showed that preoperative chemoradio- therapy reduces risk of local recurrence and death from rectal cancer compared to preoperative radiotherapy alone. Preoperative combined chemoradiotherapy, enhanced pathological response and improved local control in the resectable stage II and III rectal cancer. Preoperative chemoradiotherapy reduced the risk of local recurrence as compared with postoperative chemoradiotherapy. Postoperative radiotherapy alone did not improve survival for the patients with resected stage II and stage III rectal cancer, whereas either chemotherapy alone or combined chemotherapy and radiotherapy improved survival in comparison with observation. As compared with conventional radical surgery, total mesorectum excision (TME) resulted in lower postoperative local recurrence rate and higher survival rate. No significant differences in terms of disease-free survival rate, local recurrence rate, mortality, and morbidity were found between laparoscopic and open total mesorectal excision. Conclusion The patients with lower rectal cancer might benefit from preoperative chemoradiotherapy, postoperative chemotherapy, and chemoradiotherapy. TME is the standard rectal cancer surgery. However, long-term prognostic benefits need to be confirmed by further follow-up.
ObjectiveTo analyze the value of internal mammary lymph node biopsy via intercostal space in staging and adjuvant therapy of breast cancer.
MethodsThe clinical data of 305 breast cancer patients received any kind of radical mastectomy from may 2003 to January 2014 in the Jinan Military General Hospital of PLA were analyzed retrospectively. The patient age, axillary lymph node, and internal mammary lymph node status were integrated to investigate the changing of staging and postoperative adjuvant therapy of the breast cancer.
ResultsThese 305 patients were divided into neoadjuvant chemotherapy group and non-neoadjuvant therapy group. There were 67 patients in the neoadjuvant chemotherapy group, including 45(67.2%) patients with axillary lymph node positive, 23(34.3%) patients with internal mammary lymph node positive. There were 23(34.3%) patients who had a change of pathology lympy node (pN) staging and 8(11.9%) patients who had a change of the pTNM staging. Meanwhile, there were 238 patients in the non-neoadjuvant chemotherapy group, including 155(65.1%) patients with axillary lymph node positive, 30(12.6%) patients with internal mammary node positive. There were 30(12.6%) patients who had a change of the pN staging and 23(9.66%) patients who had a change of the pTNM staging. There was a significant difference in the metastasis rate of the internal mammary lymph node (χ2=15.7, P < 0.05) or the changing ratio of the pTNM staging (χ2=5.3, P < 0.05) in two groups.
ConclusionsInternal mammary lymph node status could affect pN staging of breast cancer, so do the pTNM staging (TNM, pathology tumor, lymph node, metastasis). The internal mammary lymph node status could guide the postoperative adjuvant radiative therapy by reducing excessive treatment of the internal mammary lymph node area, also could enhance the individual accurate therapy.
【Abstract】 Objective To summarize the effectiveness of surgical removal combined with adjuvant therapy onthe aural region keloid. Methods From January 2000 to December 2005, 42 patients (71 side ears) with keloid at the auralregion were treated. There were 8 males and 34 females, aged 16 to 50 years (mean 26.2 years). The course of diseaseranged from 6 months to 4 years. The causes of disease included earhole piercing (n=32), ear trauma(n=7), and postoperativehyperplasia(n=3); the sizes of keloids ranged from 0.3 cm × 0.3 cm× 0.2 cm to 6.0 cm × 4.0 cm × 1.0 cm with globular, dumb-bell,nodular shapes. According to the different sizes and the range of keloids, different operations to remove the keloids and repairthe defect tissue were chosen. Wounds were exposed to the electron beam at first 24 hours after operation, once a day at 2 Gyeach time for 10 days. An immediate local injection for the keloid with hormones anti-scar drugs, which was a mixture of Betamethasone(Diprospan) and 2% Lidocaine with a proportion of 1 ∶ 3, was given to the patients who had recurrence trend 3 times,every 3 weeks. Results After operation, all the wounds healed by first intention. And 37 cases(64 lateral ears) were followedup for 1 year, and all achieved cl inical cure. Five cases (7 lateral ears) had the trend of recurrence 3-6 months after operation andwere cured after the immediate local injection for the keloid with hormones anti-scar drugs. According to LIU Wenge’s curativecriterion, 37cases were cured and 5 cases responded to treatment. Conclusion Surgical removal combined with local radiationand hormones infiltrated individually as early as possible can effectively treat aural region keloids. And it is an optimal method.
Four pigs underwent the hepatic arterial infusion with 32P glass microsphere (32PGM) and pigs were killed in 15th, 30th and 90th days separately. Pathological study showed that in early stage there were many small necrotic areas scattered along the hepatic arterioles. Three months later, these necrosis were gradually absorbed and replaced by regenerating hepatic cells. Tumor-inhibition experiment was performed in 40 Bal B/C mice bearing H22 hepatoma. Intratumoral injection of 0.2ml of 32PGM/glycerine suspension (group A, n=20) or 0.2ml of blank glass microsphere/glycerine suspension (group B, n=20) were performed. The average survival time in group A and group B was 24.8 and 11.8 days respectively. Five mice in group A were alive beyond 40 days after treatment, disappearance of tumor was found in two of them. This experiment demonstrates that 32PGM is effective for treatment of experiment hepatoma. The damage to hepatic tissue after infusion is associated with the irregular distribution of microsphere, and this lesion can completely recover within three months.
Objective:To observe the therapeutic effi cacy of chemotherapy combin ed with ophthalmic therapy on retinoblastoma (RB).
Methods:The survival rate, eye ball remaining rate, and the control of the disease condition of 37 patients (56 eyes) with RB were retrospectively analyzed. The standard of the well contr ol of the disease included: (1) the ocular tumor shrank or even disappeared, and the tumor had creamlike changes or calcification and cicatrisation; (2) no oc u lar tumor recurrence in patients who had undergone enucleation; (3) no metastasi s found in the followup period. All of the patients had at least one eye with RB (ge;Ⅲb stage) underwent c hemotherapy. According to the response of the tumor to the chemotherapy, the pat ients generally underwent 6 times of systemic chemotherapy at regular intervals of 3-4 weeks. The medicines for chemotherapy included vincristine, cyclohosphamide , etoposide phosphate, and carboplatin. According to the self condition, the pati ents underwent chemotherapy combined with several ophthalmic therapies like phot ocoagulation, cryotherapy, transpupillary thermotherapy, 106Ru brachytherapy, en ucleation, etc. The observation duration lasted 2-59 months, with the average o f 35 months.
Results:Thirty patients (83.3%) survived and were followed up, and 6 died (16.6%). One patient with bilateral tumor couldn't be followed up afte renucleation of both eyes. Among these 30 patients (45 eyes), eye ball remainin g rate at stage I-Ⅱ, Ⅲ-Ⅳ, and Ⅴ was 100% (10 eyes), 70% (10 eyes), and 14 .3% (21 eyes), respectively. In the followup duration, the disease in all of the 3 0 patients was controlled well.
Conclusions:Chemotherapy combi ned with ophthalmic therapy is effective on RB.
ObjectiveTo systematically evaluate the efficacy of neoadjuvant chemoradiotherapy or chemotherapy followed by surgery versus definitive chemoradiation in stage ⅢA-N2 non-small cell lung cancer (NSCLC).MethodsWe searched PubMed, EMbase, Web of Science and The Cochrane Library to collect clinical studies on the efficacy comparison between neoadjuvant chemoradiotherapy or chemotherapy followed by surgery and definitive chemoradiation in stage ⅢA-N2 NSCLC from inception to September 2022. The meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 9 studies (3 randomized controlled trials and 6 retrospective cohort studies) with 12 801 patients were included. The results of meta-analysis showed that there was no statistical difference in the progression-free survival rate between the inductive treatment followed by surgery (including lobectomy and pneumonectomy) and definitive chemoradiation (HR=0.99, 95%CI 0.86-1.15, P=0.91). Compared with definitive chemoradiation, the overall survival (OS) rate in the inductive treatment followed by surgery (including lobectomy and pneumonectomy) was lower (HR=1.24, 95%CI 1.09-1.42, P=0.001), while the OS rate in the inductive treatment followed by lobectomy was higher (HR=0.55, 95%CI 0.51-0.61, P<0.000 01). And the local recurrence rate in the inductive treatment followed by surgery was reduced (OR=0.44, 95%CI 0.36-0.55, P<0.000 01).ConclusionNeoadjuvant chemoradiotherapy or chemotherapy followed by lobectomy is superior to definitive chemoradiation in OS and it has a lower local recurrence rate, so lobectomy should be one of the multidisciplinary treatments for selected ⅢA-N2 NSCLC patients.
ObjectivesTo explore the efficacy of simultaneous chemoradiotherapy combined with surgery for locally advanced cervical patients and perform multivariable analysis.MethodsA total of 130 cases of patients with locally advanced cervical cancer who were admitted to the Second Affiliated Hospital of Fujian Medical University from June 2012 to December 2016 were randomly divided into case group and control group. The patients in the control group were treated with platinum-based radical concurrent chemoradiation. In the case group, patients received both treatment in the control group with the addition of extensive hysterectomy and pelvic lymph node dissection. The short-term efficacy and survival outcomes of the two groups were compared.ResultsThe present study was the final report of this randomized controlled trial. 68 patients were randomly enrolled into the case group and 50 patients into control group. The non-microscopic residual tumor (non-MRT) rates were 83.8% (57/68) and microscopic residual tumor (MRT) rates were 2.9% (2/68) in the experimental group. There was no significant difference between two groups (χ2=0.008, P=0.928) in 3-year progression-free survival rate (65.6%vs. 59.6%) and 4-year progression-free survival rate (52.5% vs. 56.3%). And there was no significant difference between two groups (χ2=0.361, P=0.548) in 3-year overall survival rate (80.3%vs. 74.6%) and 4-year overall survival rate (77.6% vs. 64.9%). Multivariable analysis showed that only tumor size and parametrial invasion were significant prognostic factors of PFS (P<0.05). And only parametrial invasion was a potential prognostic indicator affecting OS (P=0.078).ConclusionParametrial invasion is an important prognostic factor. Radical concurrent chemoradiotherapy combined with surgical treatment of locally advanced cervical cancer has not significantly improved progression-free survival and overall survival. The treatment regimen should be applied with caution and selectivity.
Radiotherapy is the prior treatment for uveal melanoma, but a major problem confronted most of the patients is radiation retinopathy, which accompanied with severe visual loss and secondary enucleation potential. There is no optium choice and normative strategy so far, the intraocular melanoma society has focused on application of anti-vascular endothelial growth factor drugs injection and glucocorticoids. This article reviews a series of potential managements for radiation retinopathy and its further stage .
