RESUMO
Objective: To measure the comprehensive geriatric assessment (CGA) in elder non-Hodgkin's Lymphoma (NHL) patients in a cross-sectional study; to compare the differences between Eastern Cooperative Oncology Group (ECOG)-performance status (PS) and CGA. Methods: CGA stratification included the following 3 instrument assessments: activity of daily living (ADL);instrumental activity of daily living (IADL);comorbidity score according to the modified cumulative illness rating score for geriatrics (MCIRS-G). According to CGA and age, NHL patients, aged ≥60 years, were classified as"fit","unfit"and"frail"groups. ECOG-PS was evaluated and compared with CGA. Results: According to CGA, 51.6% senior NHL patients (33 cases) were classified as"fit", 12.5%(8 cases) as"unfit"and 35.9%(23 cases) as"frail". Several comorbidities were observed in majority patients, such as cardiovascular disease, diabetes mellitus and hypertension. In the"younger aged"patients between 60 to 64ys, 25%(3/12) was considered as"frail". However, this proportion increased to 42.9%(6/14) in patients older than 80ys. Moreover, impaired CGA was observed in 38.9%(21/54) of ECOG-PS ≤1 patient. Conclusions: Impaired CGA is as common as approximately half in elderly NHL patients and more than one third even in ECOG-PS ≤1 patients. ECOG-PS may underestimate the impaired fitness function in elder NHL patients.

Objective: In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction. Methods: In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups. Results: There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant (t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ²=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences (Z=0.406, P=0.685). Conclusions: Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.

Radical gastrectomy with D2 lymphadenectomy has been widely performed as the standard surgery for patients with gastric cancer in major medical centers in China and abroad. However, the exact extent of lymph node dissection is still controversial. In the latest version of the Japanese Gastric Cancer Treatment Guidelines, No. 14v lymph nodes (along the root of the superior mesenteric vein) are again defined as loco-regional lymph nodes, and it is clarified that distal gastric cancer presenting with infra-pyloric regional lymph node (No.6) metastasis is recommended for D2+ superior mesenteric vein (No. 14v) lymph node dissection. To explore the relevance and clinical significance of No.6 and No.14v lymphadenectomy in radical gastric cancer surgery, a review of the national and international literature revealed that No.6 lymph node metastasis was associated with No.14v lymph node metastasis, that No.6 lymph node status was a valid predictor of No.14v lymph node negative status and false negative rate, and that for gastric cancer patients with No. 14v lymph node negative and No.6 lymph node positive, the dissection of No.14v lymph node may also have some significance. The addition of No. 14v lymph node dissection in radical gastrectomy is safe, but it is more important to distinguish the patients who can benefit from it. Professor Liang Han of Tianjin Medical University Cancer Hospital is currently leading a multicenter, large-sample, prospective clinical trial (NCT02272894) in China, which is expected to provide higher level evidence for the clinical significance of lymph node dissection in No.14v.

Mesoporous slit-structured NiO materials were prepared through a simple hydrothermal route with sodium dodecyl benzene sulfonate (SDBS) as an additive. The as-prepared NiO samples presented high specific capacitance of over 1700 F g(-1) in the potential range from 0.10 to 0.56 V (vs. Hg/HgO/6 mol L(-1) KOH) at a constant current of 2 A g(-1), and good capacitance retention of â¼90% after 1000 continuous charge-discharge cycles. Only the NiO electrode materials with uniform slit-structured mesopores, which were confirmed through nitrogen adsorption-desorption isotherms and high-resolution transmission electron microscope, delivered excellent capacitances far beyond any previous report up to now. Pore structures (including pore shape, size, and distribution) are dominant factors in pseudocapacitor materials.
RESUMO
The incidence of adenocarcinoma of esophagogastric junction (AEG) is increasing at home and abroad. Laparoscopic surgery has gradually become the main means of surgical treatment of this kind of tumor. However, due to the special anatomical position of the tumor, the high position away from the broken esophagus and the narrow space in the mediastinum, laparoscopic anastomosis has the characteristics of difficult anastomosis and high anastomosis position. There is a high risk of anastomotic leakage after operation, which may cause serious consequences. Early identification of anastomotic leakage and unobstructed drainage by various means are the key to treatment. With the development of endoscopic technology, endoscopic methods such as covered stent and vacuum-assisted closure further improve the treatment efficacy. As a salvage measure, surgical treatment can achieve good treatment outcome, while accompanied by risk of complications and mortality, so we must strictly grasp the indications.

With the increase of people's health awareness and the progress of medical diagostic technology in recent years, the diagnosis rate of early gastric cancer is increasing year by year. Although radical surgery has good efficacy, how to maximize the preservation of the normal anatomy and function of the stomach and improve the quality of life of patients in the pursuit of radical surgery has become a more important issue in the treatment of early gastric cancer. Under the condition of ensuring radical lymph node dissection, function-preserving gastrectomy can fully preserve gastric function by reducing the resection extent and preserving the pylorus and the vagus nerve, which has advantage of improving quality of life and has great potential in the treatment of early gastric cancer. However, there is no functional evaluation standard for function-preserving gastrectomy at present. Most of the patients are evaluated by quality of life scale, which is relatively subjective. Even though the evaluation of endoscopy, hematology and other objective means can indicate the benefit degree in quality of life brought by functional reconstruction, the evidence level is limited. Therefore, this paper discusses the research status of function-preserving gastrectomy evaluation, postoperative complications, postoperative nutritional status, auxiliary examination and other items in the evaluation of gastric function, and analyzes the prospects of research direction in this field.

During a 15-month period, 92 patients undergoing 129 treatment episodes of immunotherapy with interleukin-2 (IL-2) alone or with immune cells underwent insertion of central venous catheters (CVCs) in the Surgery Branch, National Cancer Institute. Before each catheter insertion patients were prospectively randomized into one of three treatment groups; therapy with intravenous (IV) placebo using D5W, IV oxacillin, or change of the catheter to a new site every 72 hours. The mean duration of catheterization was 3.8 +/- 1.1 days. No patient in the oxacillin arm developed catheter-related sepsis, while eight patients in the control arms (five, line change, three, placebo) developed catheter-related sepsis (P2 = .050). Seven episodes of catheter-related sepsis were due to Staphylococcus aureus and one was due to Staphylococcus epidermidis. Catheter colonization was reduced significantly in the oxacillin arm versus control arms (P = .0001). Staphylococcus aureus, Staphylococcus epidermidis, and other coagulase-negative Staphylococci were sensitive to oxacillin in 89%, 60%, and 50% of cultures, respectively. No evidence of bacterial overgrowth, candida colonization, or candidemia was observed in these patients. Thus this trial demonstrates that treatment with prophylactic oxacillin can decrease the incidence of catheter-related sepsis in patients undergoing immunotherapy with interleukin-2 (IL-2). To our knowledge this is the first prospective randomized trial to evaluate the prophylactic use of systemic antibiotics in the prophylaxis of CVC sepsis.

BACKGROUND: Technetium 99m sestamibi is an isonitrile radionuclide imaging agent that, when used with subtraction iodine 123 thyroid scans, has the potential for imaging abnormal parathyroid glands. METHODS: We prospectively evaluated 20 patients with hyperparathyroidism to study the efficacy of Tc 99m sestamibi and 123I subtraction radionuclide scanning for the imaging of abnormal parathyroid glands. All patients underwent neck exploration and histologic confirmation of all parathyroid glands identified. RESULTS: The solitary adenomas in 11 of 16 patients with primary hyperparathyroidism were localized with sestamibi scans. The scans in four of five patients with diffuse parathyroid hyperplasia showed bilateral localization consistent with enlarged glands. The fifth patient previously underwent a subtotal parathyroidectomy, and a fifth supernumerary gland was localized with the sestamibi scan. Four patients had hyperparathyroidism related to kidney disease. Three of these had bilateral localization of enlarged glands. The fourth patient had undergone two previous operations, and a fifth supernumerary gland was localized with the sestamibi scan. CONCLUSIONS: The preliminary data indicate that Tc 99m sestamibi in combination with 123I radionuclide scanning may be useful in the preoperative localization of abnormal parathyroid glands. This technique localized all of the solitary adenomas that were subsequently resected, and in two reoperative cases it identified the remaining solitary gland causing persistent hypercalcemia.

BACKGROUND: The cost effectiveness of preoperative localization in cases of primary hyperpara-thyroidism has not been established. We analyzed the potential savings in operative time after localization with technetium 99m (99mTc) sestamibi scan. METHODS: Thirty-three patients had localization of a solitary adenoma with 99mTc-sestamibi. Measurement was made of the time required for adenomectomy, unilateral neck exploration (UNE), unilateral neck exploration and confirmation of one contralateral parathyroid gland (UNEC), or bilateral neck exploration (BNE). RESULTS: The total operative time in minutes was 76.4 +/- 18.8 for adenomectomy; 87.5 +/- 20.4 for UNE; 105.6 +/- 25.0 for UNEC; and 117.9 +/- 26.7 for BNE. The time difference was significant between adenomectomy versus UNE, UNEC, and BNE. There were also significant time differences between UNE versus UNEC and BNE. CONCLUSIONS: The preoperative localization of a solitary parathyroid adenoma may optimize operative time with UNE, saving approximately 30 minutes.

Recent developments in protein and genetic engineering methods have allowed the production of antibody-derived molecules that have important potential as therapeutic agents. Although monoclonal antibodies of murine origin have been used for therapeutic purposes, limitations due to anti-antibody responses and suboptimal effectiveness for some indications, such as tumor cell killing, have led to the development of human monoclonal antibodies, chimeric and complementarity determining-region grafted antibodies, immunotoxins, and other engineered products. These novel antibodies are being tested for the treatment and prevention of infectious diseases and for the diagnosis and treatment of cancers, as well as for indications considered nontraditional for antibodies (e.g., as antithrombotics or inhibitors of neutrophil adherence). The availability of antibody drug products raises a number of issues for clinicians. Among these are new patterns of adverse effects, immunogenicity (development of anti-antibody response), important questions regarding administration and dosage, and substantial cost implications.

Surgery for primary hyperparathyroidism is successful in 95% of patients, but ectopic glands and anatomic variations in location are causes of surgical failure. The radionuclide imaging agent, technetium (Tc)-99m-sestamibi, in conjunction with subtraction iodine-123 scanning, is a new method of preoperative localization of abnormal parathyroid glands. In a study approved by the Institutional Review Board, 22 patients with primary hyperparathyroidism underwent preoperative evaluation with high-resolution ultrasonography and Tc-99m-sestamibi/I-123 radionuclide scanning for attempted localization of abnormal parathyroid glands. Results of Tc-99m-sestamibi scanning and ultrasound were correlated with surgical and pathologic findings. Of 22 patients, 16 had a solitary parathyroid adenoma, 1 had a double adenoma, and 5 had diffuse parathyroid hyperplasia. The Tc-99m-sestamibi/I-123 radionuclide scan preoperatively identified a solitary adenoma in 14 of 16 patients (sensitivity: 88%). However, when the data were analyzed retrospectively along with surgical and pathologic findings, the Tc-99m-sestamibi scan correctly localized all parathyroid adenomas for a sensitivity of 100%. The one patient with a double adenoma had a localization image consistent with two enlarged glands. All patients with diffuse parathyroid hyperplasia had Tc-99m-sestamibi imaging consistent with diffuse hyperplasia, although delineation of individual enlarged glands was not possible. High-resolution ultrasound identified 11 of 16 parathyroid adenomas (sensitivity: 69%). The patient with a double adenoma had a negative ultrasound. Ultrasound was less accurate in five patients with diffuse hyperplasia: one scan was completely negative, two scans revealed only one enlarged gland, and two scans revealed two enlarged glands. The Tc-99m-sestamibi/I-123 subtraction radionuclide scan is more sensitive than high-resolution ultrasonography for the preoperative localization of abnormal parathyroid glands. Tc-99m-sestamibi/I-123 radionuclide scanning may be more useful than ultrasonography to the surgeon in the preoperative localization of abnormal parathyroid glands.

BACKGROUND: Because of its successful localization of solitary adenomas, 99m-Technetium sestamibi (MIBI) may challenge the standard operation for primary hyperparathyroidism. METHODS: Thirty-five consecutive patients underwent preoperative MIBI localization to optimize a surgical approach. Single-site localization in 21 patients directed a limited unilateral neck exploration (UNE) with adenomectomy and ipsilateral gland biopsy. Fourteen patients who did not localize underwent bilateral neck exploration (BNE). Conversion to a bilateral operation was required in 1 UNE patient because no adenoma was found on that side. RESULTS: There were no significant differences in preoperative and postoperative serological markers between the two groups. However, the total operative time for UNE (49 +/- 21 minutes) was significantly less than for BNE (103 +/- 45 minutes; P <0.001). CONCLUSIONS: Preoperative MIBI scan-directed limited unilateral neck operation may be used reliably for primary hyperparathyroidism due to a single adenoma, and thereby reduce operative time, extent of surgical dissection, and risk.

A thorough knowledge of parathyroid embryology and anatomy is essential for maximum success in restoration of calcium homeostasis in those patients who have a form of hyperparathyroidism. In fact, an initial meticulous neck dissection by a competent parathyroid surgeon who is well versed in the embryology and anatomy of the neck is the current "hi tech" method of choice for parathyroid gland localization.

Tc-99m-sestamibi has been shown to localize parathyroid adenomas effectively, but controversy continues as to the use of this scan before initial surgery for primary hyperparathyroidism. We analyzed the cost utility of obtaining this study before initial surgery for primary hyperparathyroidism. Twenty-two consecutive patients with primary hyperparathyroidism underwent dual-phase Tc-99m-sestamibi scan before initial bilateral neck exploration. Surgical findings were correlated with the results of sestamibi scan. There were 15 women and 7 men, with a mean age of 50.5 years (range, 22-76). Preoperative mean total calcium was 11.74 mg/dL (range, 10-15), ionized calcium was 6.19 mg/dL (range, 5.2-7.7), and intact parathyroid hormone was 153.5 pg/mL (range, 83.1-551). Postoperative mean ionized calcium was 4.56 mg/dL (range, 4.1-5.57). Twenty sestamibi scans had a positive localization, and 2 scans had no localization. At surgery, 18 solitary adenomas, 3 diffuse hyperplasias, and 1 patient with four normal parathyroid glands were found. Sixteen sestamibi scans were true positive (solitary adenoma), 4 scans were false positive (2 diffuse hyperplasia, 1 wrong side, and 1 lymph node), 1 negative scan was true negative (diffuse hyperplasia), and 1 negative scan was false negative (adenoma). One patient (four normal glands) at the second operation had a supernumerary fifth gland adenoma excised from the mediastinum. Preoperative Tc-99m-sestamibi scan did not offer any advantage when a complete bilateral neck exploration is performed. Sixteen of (84%) adenomas were correctly localized, but 18 of 19 adenomas were in the neck and were easily found. The 1 ectopic adenoma was not found by scanning or with initial surgery. The 4 of 22 (18%) false-positive localizations and the 2 of 22 (9%) negative scans contributed nothing to the surgery. Of the 22 localizing sestamibi scans, surgery was not altered to affect the outcome. At a cost of $550 per sestamibi scan and with the error inherent in the scan, it is not cost effective to obtain Tc-99m-sestamibi scan before initial surgery for primary hyperparathyroidism.

Benign ectopic thyroid tissue is a rare entity. The etiology is related to the embryological development and maturation of the thyroid gland. It is important to consider metastatic thyroid carcinoma when ectopic thyroid tissue is identified. We present two cases of nonmalignant ectopic thyroid tissue.

Breast cancer is the leading malignancy in women in the United States. Tumor size and nodal metastases have been the most important predictors of patient outcome and determinants of treatment, but have also been used to predict metastatic potential. This study was undertaken to ascertain the predictive value of flow cytometry for lymph node or systemic metastases. From 1994 through 1997, surgical specimens from 106 women who underwent treatment for invasive breast cancer were reviewed. Epidemiological data, tumor stage, nodal metastases, and flow cytometric data were collected. Analysis of variance and Student's t test were used to determine whether the presence of nodal metastases or distant metastases correlated with high S phase values and aneuploidy. Of the 106 patients studied, the mean age was 57 years; tumor size consisted of 35 per cent T1, 48 per cent T2, 8 per cent T3, and 9 per cent T4. Node status was found in the following distribution: 56 per cent node negative, 38 per cent N1, and 6 per cent N2. Distant metastases were present in four patients. Elevated S phase (defined as >9.0%) was present in 72 per cent of the population. Fifty-six per cent of these tumors were aneuploid. Node-negative patients had an elevated S phase in 66 per cent of cases, whereas node-positive patients had an elevated S phase in 71 per cent of cases. Neither S phase (P = 0.91) nor DNA index (P = 0.99) proved to be statistically significant in determining axillary node status. Neither did S phase (P = 0.87) nor DNA index (P = 0.48) consistently predict the presence of distant metastases. There is no statistical correlation between axillary node status and flow cytometric data. Breast cancers with high S phase values and aneuploid features do not reliably have axillary nodal metastases, and this data cannot replace that information provided by axillary node dissection. Synchronous systemic metastatic disease is also not predicted by flow cytometry.

Hyperparathyroidism is often detected in the asymptomatic stage at the present time with the advent of mass screening for hypercalcemia. There may be patients with parathyroid disease who are asymptomatic and who do not have detectable elevations of their serum calcium. Many patients who undergo surgery for thyroid conditions may have synchronous parathyroid disease which is asymptomatic and not detectable by routine laboratory screening. Preoperative ultrasound scans may be of utility in identifying coexistent disease in those patients scheduled for thyroid surgery so that both disease entities may be treated at the same operation.

Fine-needle aspiration cytology has a high sensitivity for the diagnosis of solitary thyroid nodules. Certain diagnoses involving follicular histologies often cannot be made with needle biopsy alone. The utility of frozen-section examination of thyroid nodules, with particular regard to those lesions with follicular histologies, is also limited. We examined the correlation of fine-needle aspiration cytology and frozen-section examination in solitary thyroid nodules to determine the contribution of frozen-section examination to the operation. We reviewed the fine-needle aspiration cytology, frozen-section examination, and final pathology of 100 consecutive patients undergoing thyroidectomy for a solitary solid thyroid nodule in an 4-year period. The diagnoses were classified as indeterminant, benign, or malignant. The utility and impact of the diagnosis from fine-needle aspiration or frozen section on the operative procedure performed was analyzed. Fine-needle aspiration cytology as a diagnostic test for thyroid nodules demonstrated an indeterminant rate of 23 per cent, with a diagnostic accuracy of 77 and 92 per cent for benign and malignant disease, respectively. In all patients with inaccurate benign diagnosis on fine-needle aspiration cytology, follicular neoplasm was misinterpreted for follicular adenoma or multinodular goiter. In comparing frozen-section results, the indeterminant, benign, and malignant rates were 7, 96, and 64 per cent, respectively. Of the 23 patients with indeterminant results on fine-needle aspiration cytology, the intraoperative frozen-section diagnosis on 4 patients was deferred to permanent section; 18 received accurate cytological diagnosis; and in 1 patient, carcinoma was missed. Overall, the decision about the extent of surgical thyroid resection was changed in only 2 patients based on the frozen-section results. Preoperative evaluation with fine-needle aspiration cytology can accurately and appropriately define the extent of thyroid surgery in most patients with a diagnosis of malignant neoplasm or benign disease. Intraoperative frozen-section examination may be helpful if fine-needle aspiration cytology results are inderminant and in cases of follicular histology as an adjunct for evaluation of the thyroid nodule, but overall, frozen section does not contribute to the management of the thyroid lesion at the time of surgery.

Despite increasing public awareness and widespread availability of mammography, many patients will present with locally advanced breast cancers. The role of surgery remains controversial. Between 1993 and 1998, 47 of 393 (11.9%) breast cancer patients presented with T4 (inflammatory or locally advanced) carcinoma. We reviewed multimodality management, clinical response to neoadjuvant therapy, perioperative course and complications, and local control. Forty-six women and one man were diagnosed with clinical T4 breast cancer. There were 24 white and 23 African-American patients. Mean age at presentation was 54.5 (range, 31-88) years. Twenty-three patients had clinical metastases to axillary nodes, and five had distant metastases at the time of diagnosis. For these women, intent was for personal hygiene and control of pain. Neoadjuvant chemotherapy was given for 34 of 47 (72%) with 25 of 34 (73.5%) having partial or complete clinical response. There was no response or progression of disease in 9 of 34(26.5%). Forty-six patients underwent radical or modified radical mastectomy, whereas a single patient underwent breast conservation treatment. Twelve required tissue transfer for wound coverage. Although eight developed minor wound complications (cellulitis/flap separation), there were no major wound complications. Pathologically negative margins were achieved in all but one patient. To date, five women have developed local recurrence in either the chest wall (three) or axilla (two). Average time to local recurrence was 7.8 months. There is no evidence of local failure in the remaining 87 per cent. Locally advanced breast cancer is a common occurrence in certain populations. Multimodality management remains the standard of care. Surgical resection may allow for successful local control and, in certain situations, long-term cure.
