Primary umbilical melanoma is rare tumor, representing about 5% of all umbilical malignancies.The lymphatic drainage from the tumor is challenging and can be to inguinal, axillary and retroperitoneal nodes. Dynamic and static lymphoscintigraphy with single-photon emission tomography/computed tomography (SPECT/CT) and sentinel lymph node biopsy (SLNB) is a widely validated technique in patients with clinically localized melanoma to search for and quantify nodal spread of cutaneous melanoma. Moreover, it offers the surgeon the preoperative information about the number and location of the sentinel lymph nodes (SLNs), which makes SLNB easier and quicker. This is the first report of an ulcerated thick melanoma of the umbilicus metastasizing only to an external iliac lymph-node without involvement of superficial inguinal SLNs. The preoperative high-resolution ultrasound (HR-US) examination of the regional lymph node field had been normal. This case-report shows how addition of SPECT/CT to planar imaging in a patient with clinically localized umbilical melanoma can help avoid incomplete SLNB when a deep SLN is not removed. A literature review of umbilical melanoma is also provided.

Medical records were searched for dogs that had received curative intent surgery for oral malignant melanoma and ipsilateral excisional regional lymph node biopsy. Twenty-seven dogs were operated on and 25 dogs of these dogs met the inclusion criteria of signalment, post-excision margin status, presence of metastasis for each biopsied lymphocentrum, survival time post-excision, presence of recurrence or metastasis at follow-up or at death/euthanasia, location of the primary tumor, and any postoperative adjuvant treatment. These 25 dogs had complete tumor excision with tumor-free margins and 19 (76%) had postoperative adjuvant therapy. Median survival time after excision for the dogs in this study was 335.5 days. Results of this study support previous work that documents prolonged survival time following complete excision of oral malignant melanoma with tumor-free surgical margins in dogs. Additionally, 4 dogs (16%) had histologically confirmed regional lymph node metastasis at the time of definitive surgery.

BackgroundThe European Society of Gynaecological Oncology (ESGO) and partners are committed to improving the training for gynecologic oncology fellows. The aim of this survey was to assess the type and level of training in cervical cancer surgery and to investigate whether the Laparoscopic Approach to Cervical Cancer (LACC) trial results impacted training in radical surgery for gynecologic oncology fellows.MethodsIn June 2020, a 47-question electronic survey was shared with European Network of Young Gynaecologic Oncologists (ENYGO) members. Specialist fellows in obstetrics and gynecology, and gynecologic oncology, from high- and low-volume centers, who started training between January 1, 2017 and January 1, 2020 or started before January 1, 2017 but finished their training at least 6 months after the LACC trial publication (October 2018), were included.Results81 of 125 (64.8%) respondents were included. The median time from the start of the fellowship to completion of the survey was 28 months (range 6–48). 56 (69.1%) respondents were still fellows-in-training. 6 of 56 (10.7%) and 14 of 25 (56.0%) respondents who were still in training and completed the fellowship, respectively, performed ≥10 radical hysterectomies during their training. Fellows trained in an ESGO accredited center had a higher chance to perform sentinel lymph node biopsy (60.4% vs 30.3%; p=0.027). There was no difference in the mean number of radical hysterectomies performed by fellows during fellowship before and after the LACC trial publication (8±12.0 vs 7±8.4, respectively; p=0.46). A significant reduction in number of minimally invasive radical hysterectomies was noted when comparing the period before and after the LACC trial (38.5% vs 13.8%, respectively; p<0.001).ConclusionExposure to radical surgery for cervical cancer among gynecologic oncology fellows is low. Centralization of cervical cancer cases to high-volume centers may provide an increase in fellows’ exposure to radical procedures. The LACC trial publication was associated with a decrease in minimally invasive radical hysterectomies performed by fellows.

This study aimed to investigate the clinical effect of ultrasound-guided ropivacaine combined with butorphanol continuous paravertebral block in preventing postoperative pain syndrome of breast cancer. For this purpose, 100 women treated for breast cancer from April 2018 to July 2019 were enrolled as research objects. Surgical procedures included local sentinel lymph node biopsy, mastectomy, sentinel lymph node biopsy for mastectomy, modified radical mastectomy, and implantation. The selected patients were randomly divided into two groups: control group (routine operation anesthesia; n = 50) and observation group (ultrasound-guided thoracic paravertebral block before induction of ropivacaine+butorphanol anesthesia; n = 50). The Real-time PCR technique was performed to evaluate CCL2 gene expression. VAS scores were recorded during the postoperative period. Compared with the control group, the observation group had lower VAS scores at six h, 24h, and 48h (P<0.05). The pain effect of the observation group was less than that of the control group. The observation group had better analgesic effects after anesthesia. The observation group had a lower incidence of pain syndrome at the 6th, 8th, and 12th months (P<0.05), and the incidence of pain syndrome in the two groups decreased with the extension of time. The observation group had lower levels of related factors (P<0.05), and the observation group had lower traumatic stress responses. The protein expression of IL-6, IL-17, and CRP in the observation group was lower than that in the control group (P<0.05). The results of CCL2 gene expression also showed that gene expression in the control group increased significantly (P=0.0047). Since the expression of this gene is one of the factors that stimulate pain signals in the body, the method used in the present study was able to reduce the amount of pain significantly. Therefore, the combination of ropivacaine combined with butorphanol ultrasound-assisted paravertebral block can reduce the intensity of postoperative pain in patients with breast cancer surgery, decrease the incidence of pain syndrome, and increase pain tolerance.
