11026 Background: Retrospective study on locally advanced GCTB patients (pts) treated with neoadjuvant Denosumab (Db) outside clinical trials in 6 European reference centers. Methods: From 138 pts (median age 30yrs) with histologically confirmed advanced GCTB treated with Db(2011-2016), we included into analysis 87pts who underwent surgery after preoperative Db. All 87 patients had locally advanced tumors with extensive soft tissue involvement(54) or penetration to joint, not amenable to limb-sparing surgery/primary curettage or with high risk of recurrence. In 39/42(93%) cases diagnosis was confirmed by H3F3Agene mutation. Median follow-up time -22 months. Results: Primary tumor was located in lower limb(54%; n = 47) -mostly in tibia(25%) and femur(23%), upper limb(33%; n = 29), and pelvis/axial skeleton/ribs(13%; n = 11). 68(78%) patients had primary tumors, 19(22%) recurrent tumors after surgery (+/-radiotherapy). Median Db duration was 7months (range 1.5-35months), 17pts received also Db postoperatively. 39(45%) had wide en-bloc resection -WE (+17 implantation of prosthesis), 48(55%) cases had intralesional curettage -C, no extremity amputation. Pts who underwent prosthetic replacement had longer median preoperative Db therapy as compared to pts without prosthesis. All pts demonstrated a response to Db Progression after surgical treatment was observed in 15 pts -13 of them after intralesional curettage (13/48, 27%); 9 patients underwent D re-challenge -all responded. Two-year progression-free survival (PFS; from Db start) rate was 80%, 91% in WE group vs 73% in C group (p = 0.04), one-year PFS (from operation date) rate was 84%: 92% in WE and 79% in C group(p = 0.01). Treatment was well tolerated with only 1 grade 3 toxicity. Conclusions: Our study confirms that Db is active in a neoadjuvant setting with excellent efficacy and short-term tolerability. It implies that neoadjuvant therapy with Db is the option for treatment of initially locally advanced tumors to facilitate complete surgical resection or avoid mutilating surgery. The risk of recurrences after curettage of GCTB following Db raises questions about the optimal duration of preoperative treatment and if Db is indicated postoperatively.

181 Background: Biallelic loss of CDK12 has recently been identified as a novel subtype of prostate cancer (PCa). CDK12 altered PCa associates with elevated neoantigen burden and thus may be suitable for checkpoint inhibition. Up to now, data about CDK12 refer to its genetic alterations in PCa while its characterization on protein level and its association with tumor infiltrating T-cells are lacking. Methods: Immunohistochemistry (IHC) for CDK12 was performed on a PCa cohort including 74 benigns, 391 primary tumors from 222 patients, 63 locally advanced tumors, 92 lymph node (LN) metastases, and 56 distant metastases. CDK12 was categorized into negative, weak, moderate and high expression. Density of tumor associated T-cells per tumor area was assessed by IHC for CD3 and graduated into negative (<1%), slight (1-5%), weak (5-10%), moderate (10-50%) and high (>50%). Results: CDK12 significantly increases during PCa progression showing highest levels in LN and distant metastases while benign samples harbor no or weak CDK12 expression (ANOVA p<0.001). Kaplan-Meier curve reveals 5-year-biochemical recurrence free survival rates of 89.5%, 69.1%, 59.1% and 20.0% for primary tumors expressing no, weak, moderate and high CDK12 (log-rank p=0.05). High CDK12 expression significantly associates with attenuated tumor associated T-cells (p=0.009) revealing CD3 negativity in 64.7% of CDK12 high expressing tumors. Intratumoral CDK12 and density of CD3 positive T-cells correlates adversely in particular in locally advanced tumors (p=0.007). Overall, tumor associated T-cells are significantly reduced in distant metastases compared to local PCa (p<0.001). Conclusions: Our study highlights the prognostic potential of CDK12 for PCa and its overexpression in advanced tumors. Of note, CDK12 overexpressing tumors can be designated as immunologic “cold” tumors which is in line with their more aggressive phenotype. Concordantly, distant metastases show attenuated tumor associated T-cells supporting the poor response to immunotherapy.

Abstract Background. We report on the activity of the combination of epirubicin and docetaxel given in neoadjuvant setting for 4 and 8 cycles respectively in 2 successive series of patients with large operable or locally advanced, hormone receptor positive, HER-2 negative breast cancer. Patients and methods. Patients were treated from 2002 to 2006 with epirubicin 90 mg/m2 and docetaxel 75 mg/ m2 intravenously, every 3 weeks for 4 cycles before and 4 cycles after surgery (Series I - 13 patients), and from 2006 to 2010 with the same regimen administered for 8 cycles preoperatively (Series II - 37 patients), plus hormonal therapy for 5 years and radiation therapy if indicated. All Series I and 32 Series II patients were able to complete the preoperative chemotherapy. Results. A complete response was found in 1 patient from Series I and 13 patients from Series II and the partial remission in 10 patients from Series I and 21 patients from Series II. Two Series I and 3 Series II patients did not respond clinically. Response rate (Series I/Series II) was 84/92%. All 50 patients underwent surgery. In Series I patients, 3 pCR occurred in the breast and the axilla was histologically negative in 2 cases. No evidence of disease both in the breast and in the axilla was achieved in 7.6% (1/13) of patients. In Series II patients, 8 pCR occurred in the breast and axilla was histologically negative in 15 patients. No evidence of disease both in the breast and in the axilla occurred in 10.8% (4/37) of patients. G3-G4 toxicity included myelosuppression in 3 patients from Series I and all patients from Series II, and mucositis in 1 patient from Series I and 4 patients from series II. No other G3-4 toxicities or toxic deaths occurred. Five-year progression free survival was 38% and 90% in Series I and Series II patients respectively. Conclusions. The incidence of pathologic complete remissions was lower in our patient population, compared to reported data. A longer duration of the preoperative treatment might be associated with a longer progression-free survival.

Introduction: Surgical management of Giant Cell Tumor of Bone of the distal radius (GCTDR) remains controversial due to risk of local recurrence (LR) offset by functional limitations which result from en-bloc resection. This study aims to determine the oncologic and functional outcomes of wide excision (WE) vs intralesional curettage (IC) of GCTDR. Methods: A complete search of the applicable literature was done. Included studies reported on patients from the same cohort who were surgically treated for GCTDR with WE or IC. Two reviewers independently assessed all papers. The primary outcome measure was LR. Results: One-hundred-forty-one patients from six studies were included: 60 treated with WE, and 81 with IC. Five WE patients (8%) suffered LR whereas 25 IC patients (31%) did. The odds of LR were three times less in the WE group vs the IC group. MSTS1993 scores, where available, were on average 'good' with WE and 'excellent' with IC. Conclusions: Within statistical limitations the data support an attempt, where feasible, at wrist joint preservation and superior function with IC. Intralesional curettage is reasonable when the functional benefit outweighs the risk of recurrence as is the case in many cases of GCT of the distal radius.

Direct invasion of colorectal adenocarcinoma into adjacent structures occurs frequently, but only rarely is the duodenum involved. This study was undertaken to assess the safety and efficacy of en bloc resection of locally advanced right colon carcinoma invading the duodenum. A retrospective review of 49 patients with locally advanced colon cancer, surgically managed between 2000 and 2005, was performed. Forty-six patients underwent en bloc resection of colon and adjacent organs not involving the duodenum. Three patients with duodenal invasion underwent en bloc partial duodenectomy. The mean operative blood loss, length of stay, postoperative morbidity, and mortality compare favorably between these two groups of patients. Of the 46 patients with en bloc resection of other organs, 27 are alive at 12 to 60 months follow up. Two patients with duodenal invasion are alive without recurrence at 15 and 20 months follow up. En bloc resection of colon cancer invading the duodenum can be performed safely because morbidity and mortality rates are comparable to those attending extended resections of other locally advanced colon carcinomas. Overall survival in patients who underwent surgery with curative intent justifies en bloc duodenal resection in selected patients.

Abstract Introduction Surgery is the cornerstone for the management of giant cell tumors (GCTs). There are no definite guidelines for the management. The purpose of this series was to study the patient demography and results of the surgical intervention for skeletal GCTs in our population. Materials and Methods All the histologically diagnosed cases of GCT of bone from year 2012 to 2018 were retrospectively analyzed for patient demographics, site, and grade of the lesion, type of biopsy taken (if any), nature of surgical intervention, and final outcome with respect to complications. Results Seventeen cases of skeletal GCT were diagnosed on histopathology. The mean age at presentation was 31.5 ± 10.9 years with females affected 1.4 times more. Proximal tibia was the most common site (29.4%) followed by distal radius and distal femur in that order. About 58.8% of the lesions were of Campanacci grade 2 and remaining were grade 3 lesions. Ten patients had extended curettage, five had en bloc resection, and one had amputation as the primary treatment. Twenty percent patients (n = 3) had local recurrence of the pathology and one patient developed distant recurrence (lung metastasis). Conclusion Proximal tibia followed by distal radius was the most common site of GCT in our population. The tumor behavior and recurrence cannot be predicted with any grading system. The goal should be salvage of the joint by intralesional curettage, with resection reserved for distal radius GCTs, cases with extensive soft tissue extension or those with destruction of the articular cartilage and joint involvement.

Surgery alone, more or less demolitive, is the treatment of choice of vulvar cancers. Cure rates are high for early cancers only, while locally advanced tumors with or without inguinal adenopathies and recurrences have a bad prognosis. The excellent results of concurrent chemo-radiotherapy of anal cancers suggested to adopt the same approach for locally advanced vulvar cancers. The shrinkage of the tumor allowed surgery, often less demolitive than usual, and the pathological examination demonstrated an overall complete response in 40% of cases. Survival has been improved through this multidisciplinary approach. Patients not suitable for surgery obtained important remissions and an improved quality of life. Clinical experience at the Istituto Tumori of Milano is presented.
