The difference of the impacts of surgical approaches on cellular immunity in patients with uterine malignancies: a comparative study of laparoscopy and laparotomy surgery

Uterine sarcomas: A critical review of the literature

This review aims to provide a comprehensive description of surgical approaches for the management of uterine sarcomas. Uterine sarcomas are rare uterine neoplasms. Frequently, diagnosis is made after hysterectomy or myomectomy scheduled for presumed benign leiomyomas. The gold standard for surgical treatment of uterine sarcomas is hysterectomy with bilateral salpingo-oophorectomy. It is possible to adopt a fertility-sparing approach for those patients who wish to maintain their fertility. The role of pelvic lymphadenectomy is controversial; in fact, removal of lymph nodes is only recommended in the case of radiological suspicion of nodal involvement. Use of a morcellator is associated with increased risk of total recurrence, intra-abdominal recurrence and death. Advanced disease management should be customized based on the patient's performance status given the uncertain role of adjuvant chemotherapy. Treatment of advanced or recurrent disease remains a subject of debate, but surgery is the best approach in terms of morbidity and mortality. There are few options for management of these uterine tumours, and further studies are needed to clarify the diagnostic and therapeutic pathways of patients with a first diagnosis of uterine sarcoma and patients with relapse of uterine sarcoma. No specific evidence supports the adoption of adjuvant therapy in uterine-confined disease, and molecular/genomic profiling may be useful to identify patients at risk of recurrence.

Impact of Perioperative Multiple Doses of Glucocorticoids on Peripheral Blood Lymphocyte Subsets and Inflammatory Cytokines in Patients With Non-small Cell Lung Cancer

Purpose

Surgery-induced immunosuppression is associated with infectious complications and cancer recurrence. This study aimed to characterize the effects of perioperative multiple doses of glucocorticoids on the peripheral immune environment in patients with non-small cell lung cancer.

Methods

In this retrospective study, surgical patients with lung cancer were included. Lymphocyte subsets, lymphocyte phenotypes, lymphocyte functions, and inflammatory cytokines were evaluated in the peripheral blood preoperatively, then at 1 day and 7 days postoperatively. Levels of immune cells and inflammatory factors were compared between those who did or did not receive glucocorticoids at all time points.

Results

Multiple doses or high doses (15–20 mg dexamethasone equivalents) of glucocorticoids that were all given within 24 h were associated with decreased absolute numbers of T cells, CD4⁺and CD8⁺T cells, B cells, and impaired T cells function at 1 day postoperatively while a single intraoperative low dose (5 mg) of dexamethasone had little influence on the peripheral environment. IL-1β, IL-6, and TNF-α were also more affected by multiple doses of glucocorticoids.

Conclusions

Among patients with lung cancer, perioperative multiple doses of glucocorticoids that are all given within a short time are associated with decreased immune cell counts and impaired T cells functions.

Postoperative benefits of dexmedetomidine combined with flurbiprofen axetil after thyroid surgery

The present study determined the effect of dexmedetomidine (Dex) combined with flurbiprofen axetil (FA) on analgesia, immune response, and preservation of cognitive function in patients subjected to general anesthesia. We recruited 100 patients with thyroid surgery and randomly divided them into four groups: Dex (D), FA (F), Dex combined with FA (DF), and saline control (C). The extubation and recovery times for Groups D and DF were significantly longer than for Groups F and C. After extubation, the heart rate and mean arterial pressure for Groups F, D, and DF were significantly lower than for Group C, and data for Group DF was significantly lower than for Group F. The visual analog scale and Riker sedation agitation scores were significantly lower in Group DF than for the other three groups. T- and B-lymphocytes were significantly higher in Group DF than in the other three groups. Compared with Groups F and C, the levels of TNF-α and IL-6 in Group DF were significantly reduced, while IL-2 markedly increased. The combined use of Dex and FA significantly improved pain after general anesthesia thyroid surgery, reduced restlessness and postoperative cognitive dysfunction, enhanced immune function, and promoted wound repair.

Robotic surgery for gynaecologic cancer: an overview

After decades of reluctance to change surgical approaches, new technologies have created new perspectives for surgery. Initially, the laparoscopic approach was considered to be only one useful for relatively simple procedures as the design of the instruments and the limited access hampered free movements to perform complicated surgery. Robotic systems overcame this problem and boosted the use of minimally invasive techniques also for radical gynaecological surgery. Robot-assisted laparoscopy can now routinely be used for the surgical treatment of early or downstaged cervical carcinoma, endometrial carcinoma and staging of early ovarian carcinoma. Robot-assisted laparoscopy has proven to be feasible, although the benefits for the patient are less clear than those for the surgeon. The main advantage of robot-assisted laparoscopy over conventional laparoscopy is probably not that it is safer or better, but that it allows more types of radical surgery to be performed and that it prevents the surgeon from developing complaints and muscular conditions that interfere with the ability to perform surgery. New applications have emerged with the introduction of new devices to be used in conjunction with the robotic system as well as with totally new robotic systems. Training in these new tools should be more systematic and structured to allow their safe introduction and use.
