Outcomes of chemotherapy/chemoradiation vs. R2 surgical debulking vs. palliative care in nonresectable locally recurrent rectal cancer.

Locally recurrent rectal cancer is resected with clear margins in only 50% of cases, and these patients achieve a three-year survival rate of 50%. Outcomes and therapeutic strategies for nonresectable locally recurrent rectal cancer have been much less explored. The aim of the study was to assess the three-year progression-free survival and the three-year overall survival in locally recurrent rectal cancer patients treated by chemotherapy/chemoradiation only vs. chemotherapy/chemoradiation and R2 surgical debulking vs. palliative care. A total of 86 patients affected by nonresectable locally recurrent rectal cancer were included: three-year progression-free survival was 15.8% with chemotherapy/chemoradiation vs. 20.3% with R2 surgical debulking (Log-rank p=0.567), but both rates were higher than best palliative care (0.0%, Log-rank p=0.0004). Three-year overall survival rates were respectively 62.0%, 70.8% and 0.0% (Log-rank p<0.0001). Chemotherapy/chemoradiation (HR 0.33, p=0.028) and R2 surgical debulking with or without chemotherapy/chemoradiation (HR 0.23, p=0.005) were independent predictors of improved progression-free survival on multivariate analysis. In conclusion, both chemotherapy/chemoradiation alone and R2 surgery with or without chemotherapy/chemoradiation provide a survival benefit over palliative care in nonresectable locally recurrent rectal cancer. However, considering that pelvic debulking is burdened by a high rate of complications, and considering its negligible impact on progression-free survival and overall survival when associated to medical therapy, surgery should be avoided in this setting.

Patient satisfaction with ultrasound, whole-body CT and whole-body diffusion-weighted MRI for pre-operative ovarian cancer staging: a multicenter prospective cross-sectional survey.

BACKGROUND: In addition to the diagnostic accuracy of imaging methods, patient-reported satisfaction with imaging methods is important. OBJECTIVE: To report a secondary outcome of the prospective international multicenter Imaging Study in Advanced ovArian Cancer (ISAAC Study), detailing patients' experience with abdomino-pelvic ultrasound, whole-body contrast-enhanced computed tomography (CT), and whole-body diffusion-weighted magnetic resonance imaging (WB-DWI/MRI) for pre-operative ovarian cancer work-up. METHODS: In total, 144 patients with suspected ovarian cancer at four institutions in two countries (Italy, Czech Republic) underwent ultrasound, CT, and WB-DWI/MRI for pre-operative work-up between January 2020 and November 2022. After having undergone all three examinations, the patients filled in a questionnaire evaluating their overall experience and experience in five domains: preparation before the examination, duration of examination, noise during the procedure, radiation load of CT, and surrounding space. Pain perception, examination-related patient-perceived unexpected, unpleasant, or dangerous events ('adverse events'), and preferred method were also noted. RESULTS: Ultrasound was the preferred method by 49% (70/144) of responders, followed by CT (38%, 55/144), and WB-DWI/MRI (13%, 19/144) (p<0.001). The poorest experience in all domains was reported for WB-DWI/MRI, which was also associated with the largest number of patients who reported adverse events (eg, dyspnea). Patients reported higher levels of pain during the ultrasound examination than during CT and WB-DWI/MRI (p<0.001): 78% (112/144) reported no pain or mild pain, 19% (27/144) moderate pain, and 3% (5/144) reported severe pain (pain score >7 of 10) during the ultrasound examination. We did not identify any factors related to patients' preferred method. CONCLUSION: Ultrasound was the imaging method preferred by most patients despite being associated with more pain during the examination in comparison with CT and WB-DWI/MRI.

Long-term outcomes of lung cancer screening in males and females.

BACKGROUND: This study explored female and male overall mortality and lung cancer (LC) survival in two LC screening (LCS) populations, focusing on the predictive value of coronary artery calcification (CAC) at baseline low-dose computed tomography (LDCT). METHODS: This retrospective study analysed data of 6495 heavy smokers enrolled in the MILD and BioMILD LCS trials between 2005 and 2016. The primary objective of the study was to assess sex differences in all-cause mortality and LC survival. CAC scores were automatically calculated on LDCT images by a validated artificial intelligence (AI) software. Sex differences in 12-year cause-specific mortality rates were stratified by age, pack-years and CAC score. RESULTS: The study included 2368 females and 4127 males. The 12-year all-cause mortality rates were 4.1 % in females and 7.7 % in males (p < 0.0001), and median CAC score was 8.7 vs. 41 respectively (p < 0.0001). All-cause mortality increased with rising CAC scores (log-rank test, p < 0.0001) for both sexes. Although LC incidence was not different between the two sexes, females had lower rates of 12-year LC mortality (1.0 % vs. 1.9 %, p = 0.0052), and better LC survival from diagnosis (72.3 % vs. 51.7 %; p = 0.0005), with a similar proportion of stage I (58.1 % vs. 51.2 %, p = 0.2782). CONCLUSIONS: Our findings demonstrate that female LCS participants had lower rates of all-cause mortality at 12 years and better LC survival than their male counterparts, with similar LC incidence rates and stage at diagnosis. The lower CAC burden observed in women at all ages might contribute to explain their lower rates of all-cause mortality and better LC survival.

Long-term disease stability with bicalutamide in a man with aggressive angiomyxoma: case report and state of art.

Aggressive angiomyxoma (AA) is a rare mesenchymal neoplasm, which is commonly diagnosed in females and located in the perineal and pelvic region. Tissue specimens of AA patients often show positivity for estrogen (ER) and progesterone receptors (PgR), while some cases of androgen receptor (AR) positivity have been reported in males. When feasible, surgical excision represent the most effective treatment of AA; however, when experiencing advanced or recurrent disease, local disease control could be achieved with systemic hormonal treatment. To date, evidence regarding AA management in male patients is scarce, and only a few cases have been reported in literature. Hereby, we describe the case of a 59-year-old-man suffering from perineal AA with positivity for androgen receptors (AR) showing a long-lasting disease stability during the treatment with an AR-blocking drug (bicalutamide). A literature review regarding the state of art of AA management with a particular look to male patients is also provided.

Delayed Gastric Emptying After Multivisceral Resection for Retroperitoneal Sarcoma.

INTRODUCTION: Delayed gastric emptying (DGE) is a common complication in surgery, but incidence and relevance following multivisceral resection are unknown. METHODS: Data from 100 consecutive patients treated for primary retroperitoneal sarcoma (RPS) were analyzed from our institutional prospectively maintained database from January 2019 to April 2020. DGE severity was graded according to the International Study Group of Pancreatic Surgery and classified as primary or secondary to other complications. The primary outcome was incidence and grade of clinically relevant DGE (grades B-C). Secondary outcomes were correlation with patient, tumor, and treatment characteristics, and non-DGE morbidity [Clavien-Dindo (CD) grade ≥ 3]. RESULTS: Forty-two patients developed DGE and 28 had clinically relevant DGE. DGE was primary in 10 patients and secondary in 18 patients; the most common associated complications were: infections (11/18, 61.1%), pancreatic leak (7/18, 38.9%), bleeding (6/18, 33.3%), and bowel leak (6/18, 33.3%). DGE was related to longer length of hospital stay (P < 0.001), ICU admission (P = 0.004), ICU length of stay (P = 0.001), postoperative complications (CD [Formula: see text] 3 in 14/28 in DGE patients vs 11/72 in no-DGE; P = 0.04), and re-operation (P = 0.03). With multivariate analysis, the independent risk factors for DGE were patient comorbidities (OR 1.05; 95% CI 1.01-1.1; P = 0.04) and tumor size (OR 1.05; 95% CI 1.0-1.1; P = 0.02). DISCUSSION: Following multivisceral resection, DGE is a clinically relevant event that can be caused by an underlying complication. Prompt diagnosis and treatment of both DGE and any underlying complications led to full recovery in all cases.

Sclerosing angiomatoid nodular transformation (SANT) of the spleen: A case report on CT and MRI.

Solid tumors of the spleen are rare, with an incidence of 0.007% in all operating and autopsy specimens. In terms of microscopic structure and function, the spleen consists of two parts: the white pulp, which plays an important role in the immune system and the red pulp, which filters the blood.Primary splenic neoplasms can be classified into lymphoid neoplasms arising from the white pulp, and vascular neoplasms which arise from the red pulp.Primary tumors arising from vascular elements include benign lesions such as hemangioma, lymphangioma and hamartoma, intermediate lesions such as hemangioendothelioma, hemangiopericytoma and littoral cell angioma as well as the frankly malignant hemangiosarcoma.It is usually difficult to distinguish a benign from a malignant lesion with preoperative imaging studies and cytological exam by fine-needle aspiration (FNA), that is not easily obtained because of the risk of bleeding.Therefore a splenectomy should be necessary for a definitive diagnosis of splenic tumors.Martel and all for the first time described the sclerosing angiomatoid nodular transformation (SANT), like a vascular lesion of the spleen, with benign clinical course consisting by altered red pulp tissue that has been entrapped by a non-neoplastic stromal proliferative process.We describe a rare case of benign splenic mass documented with FDG/PET-CT (referred as equivocal), CT and MRI.

Metastatic and non-metastatic lymph nodes: quantification and different distribution of iodine uptake assessed by dual-energy CT.

OBJECTIVES: To evaluate quantification of iodine uptake in metastatic and non-metastatic lymph nodes (LNs) by dual-energy CT (DECT) and to assess if the distribution of iodine within LNs at DECT correlates with the pathological structure. METHODS: Ninety LNs from 37 patients (23 with lung and 14 with gynaecological malignancies) were retrospectively selected. Information of LNs sent for statistical analysis included Hounsfield units (HU) at different energy levels; decomposition material densities fat-iodine, iodine-fat, iodine-water, water-iodine. Statistical analysis included evaluation of interobserver variability, material decomposition densities and spatial HU distribution within LNs. RESULTS: Interobserver agreement was excellent. There was a significant difference in iodine-fat and iodine-water decompositions comparing metastatic and non-metastatic LNs (p < 0.001); fat-iodine and water-iodine did not show significant differences. HU distribution showed a significant gradient from centre to periphery within non-metastatic LNs that was significant up to 20-30% from the centre, whereas metastatic LNs showed a more homogeneous distribution of HU, with no significant gradient. CONCLUSIONS: DECT demonstrated a lower iodine uptake in metastatic compared to non-metastatic LNs. Moreover, the internal iodine distribution showed an evident gradient of iodine distribution from centre to periphery in non-metastatic LNs, and a more homogeneous distribution within metastatic LNs, which corresponded to the pathological structure. KEY POINTS: • This study demonstrated a lower iodine uptake in metastatic than non-metastatic LNs. • Internal distribution of HU was different between metastatic and non-metastatic lymph nodes. • The intranodal iodine distribution disclosed a remarkable correlation with the histological LN structure.

Successful use of rFVIIa for major breast surgery prophylaxis in congenital factor VII deficiency: a case report.

INTRODUCTION: Factor VII deficiency is a rare cause of haemorrhagic syndrome. The Authors describe a case of a 46 years old patient with congenital factor VII deficiency that successfully underwent breast surgery after treatment with Novoseven® before the procedure. MATERIALS AND METHODS: The AA used the schedule reported below to value the levels of PT and aPTT in the patient. Blood Collection: Venous blood from patient and control was collected in glass tubes for routine serum preparation and into plastic tubes (0.129 M sodium citrate, Becton-Dickinson Vacutainer Systems) in a ratio of blood to anticoagulant of 9:1. Platelet Poor Plasma (PPP) was obtained by centrifugation at 4.000 x g for 15 minutes at room temperature. The plasma was recentrifuged for another 10 min at 12000 g to fully eliminate platelet concentration. A normal control plasma pool was prepared by mixing equal volumes of platelet-free plasma obtained from at least 50 normal volunteers. Prothrombin time (PT) was measured with Recombiplastin (IL, Milano Italy). Activated partial thromboplastin times (APTT) was measured with APTT-SP (IL, Milano Italy). They were performed on the coagulation analyzer ACL 1000 (IL, Milano Italy). RESULTS: The results were interpreted from the ratio of the patient times to the normal control times (Table I). CONCLUSION: The infusion of Novoseven solved the clotting problems enabling the surgical procedure, without risks for the patient.

Cat scratch disease presenting as breast cancer: a report of an unusual case.

Benign lymphoreticulosis (cat scratch disease, CSD) may have a clinical course that varies from the most common lymphadenitis localized in the site of inoculation, preceded by the typical "primary lesion," to a context of severe systemic involvement. Among these uncommon clinical aspects, there is mammarian granulomatous lymphadenitis which may appear as a mastitis or a solitary intraparenchymal mass, giving the impression of a breast tumor. In these cases, intensive clinical, instrumental, and laboratory investigations are necessary to exclude malignancy. Because of its rarity, in equivocal cases, it is reasonable to use surgical excision for accurate histological examination. We report a case of CSD of the breast in a 59-year-old woman, analyzing the clinical, histopathological, and instrumental appearance and also performing a literature review.
