Abstract
295 Background: The optimum combination curative approach to locally advanced adenocarcinoma of the esophagus and esophago-gastric junction (AEG) remains controversial, specifically whether multimodal therapy or perioperative chemotherapy is superior. Neo-AEGIS was designed as the first randomized clinical trial (RCT) to directly compare the multimodal CROSS regimen (carboplatin/paclitaxel, 41.4Gy radiation therapy) with a modified MAGIC (epirubicin, cisplatin (oxaliplatin), 5-FU (capecitabine)) regimen (pre-2018) and more latterly the FLOT (docetaxel, 5-FU, leucovorin, oxaliplatin) regimen. Methods: 377 patients with cT2-3N0-3M0 AEG were randomly assigned to CROSS or peri-operative chemotherapy (ECF/ECX/EOF/EOX pre-2018, FLOT option 2019/20) at 24 sites (Ireland, UK, Denmark, France, Sweden). The primary outcome was overall survival. The initial power calculation was based on CROSS superiority of 10%. This was modified after the first futility analysis (70 events) to a non-inferiority margin of 5% for peri-operative chemotherapy. Secondary end points included toxicity, pathologic measures of response, and postoperative complications as per the Esophageal Complications Consensus Group (ECCG) definitions and Clavien-Dindo severity grade. Results: Of 362 evaluable patients, 178 CROSS, 184 MAGIC/FLOT (157/27), 90% were male, median (range) age 64 (35-83), 84% were cT3, and 58% cN1. At a median (range) follow up of 34.2 (0.43-111.8) months, there were 186 deaths, 91 CROSS and 95 MAGIC/FLOT arm, with 3-year estimated survival probability of 57% (95% CI 49,64) and 55% (95% CI 47,62), respectively [(HR 1.03 (95%CI. 0.77-1.38))]. Conclusions: This RCT reveals no evidence that peri-operative chemotherapy is unacceptably inferior to multimodal therapy in the primary outcome of overall survival, notwithstanding greater proxy markers of local tumor response in the CROSS arm. Oncologic and operative outcomes were consistent with optimum modern benchmarks. These data strongly suggest non-inferiority and support equipoise in clinical decision making in modern practice.

Abstract
We investigate the accuracy of intensity-based deformable image registration (DIR) for tumor localization in liver stereotactic body radiotherapy (SBRT). We included 4DCT scans to capture the breathing motion of eight patients receiving SBRT for liver metastases within a retrospective clinical study. Each patient had three fiducial markers implanted. The liver and the tumor were delineated in the mid-ventilation phase, and their positions in the other phases were estimated with deformable image registration. We tested referenced and sequential registrations strategies. The fiducial markers were the gold standard to evaluate registration accuracy. The registration errors related to measured versus estimated fiducial markers showed a mean value less than 1.6mm. The positions of some fiducial markers appeared not stable on the 4DCT throughout the respiratory phases. Markers’ center of mass tends to be a more reliable measurement. Distance errors of tumor location based on registration versus markers center of mass were less than 2mm. There were no statistically significant differences between the reference and the sequential registration, i.e., consistency and errors were comparable to resolution errors. We demonstrated that intensity-based DIR is accurate up to resolution level for locating the tumor in the liver during breathing motion.

Abstract
LBA3514 Background: Organ preserving treatment strategies based on chemoradiotherapy may spare rectal cancer patients of major surgery and stoma. We suggest substantially improved tumor control by increasing the radiotherapy dose, without significant increase in the rate of late effects. We designed a prospective phase II trial to test high-dose radiotherapy of low rectal cancer for organ preservation in a multicenter setting. Methods: We enrolled patients with localized T1-3 N0-1 M0 rectal cancer within 6 cm from the anal verge and in performance status 0-2. Any N1-nodes had to be at the level of the tumor and included in the primary tumor-volume. Radiotherapy consisted of 62 Gy to the tumor and 50.4 Gy to the regional lymph nodes, delivered in 28 fractions using intensity modulated radiation therapy and daily image guidance. Capecitabine 825 mg/m2 BID. Patients with clinical complete response (cCR) 6–12 weeks after end of treatment were allocated to follow-up. Surgery was offered only in case of residual cancer or later re-growth. The primary endpoint was the proportion of patients with locoregional tumor control after two years by chemoradiation alone. Secondary endpoints included long-term side effects (CTCAE grading), cCR, rate of distant metastases, and overall survival. Results: Three Danish centers enrolled 107 patients between 2015 and 2019. Baseline classifications were T1/T2/T3 and N1 in 15%/54%/31% and 29%, respectively. The median age was 71 years and 64% were male. 92 (86.0%) had cCR and were allocated to observation. Four patients drew consent or died leaving 103 observed for at least 2 years. 23 had regrowth after cCR, five of whom had organ preserving transanal endoscopic microsurgery, 15 other curative surgery, and three palliation. 63 had no locoregional regrowth. Thus 61% (63/103) of patients with 2 years of follow-up had locoregional tumor control with chemoradiation alone. The actuarial estimate of locoregional control at 2 years from start of observation was 73.8% (95%CI 63.2-81.8). Calculated from time of enrollment, metastasis-free and overall survival at 30 months was 85.4% (95%CI 76.5-91.1) and 94.8% (95%CI 87.8-97.8). In the 63 patients with complete response at 2 years, ‘Low Anterior Resection Syndrome-score’ was None=37%, Minor=28%, and Major=35%. The most severe toxicity was erectile dysfunction grade 3 (n=3), grade 2 (n=4), grade 1 (n=6), and grade 0 (n=26). Grade 2 diarrhea, constipation, fecal incontinence, rectal bleeding and decreased libido were each reported in one case, while urinary frequency grade 2 was seen in four patients. Conclusions: The vast majority of patients with low rectal cancer can be cured by modern radiotherapy 62 Gy in 28 fractions with excellent patient-reported outcomes, toxicity, tumor control, and survival. The treatment is feasible in a multicenter setting. We suggest this approach as a standard of care option. Clinical trial information: NCT02438839.

Abstract
4004 Background: The optimum combination curative approach to locally advanced adenocarcinoma of the esophagus and esophago-gastric junction (AEG) is unknown. A key question is whether neoadjuvant multimodal therapy, specifically CROSS (carboplatin/paclitaxel, 41.4Gy radiation therapy), is superior to optimum peri-operative chemotherapeutic regimens including modified MAGIC (epirubicin, cisplatin (oxaliplatin), 5-FU (capecitabine)) and more latterly FLOT (docetaxel, 5-FU, leucovorin, oxaliplatin). Neo-AEGIS was designed as the first randomised controlled trial to address this question. Methods: 377 patients with cT2-3N0-3M0 AEG were randomly assigned to CROSS or peri-operative chemotherapy (ECF/ECX/EOF/EOX pre-2018, FLOT option 2019/20) at 24 sites (Ireland, UK, Denmark, France, Sweden). The primary outcome was overall survival. The initial power calculation was based on CROSS superiority of 10%. This was modified after the first futility analysis (70 events) to a non-inferiority margin of 5%. Secondary end points included toxicity, pathologic measures of response, and postoperative complications as per the Esophageal Complications Consensus Group (ECCG) definitions and Clavien-Dindo severity grade. Results: Of 362 evaluable patients, 178 CROSS, 184 MAGIC/FLOT (157/27), 90% were male, median (range) age 64 (35-83), 84% were cT3, and 58% cN1. At a median (range) follow up of 24.5 (1-92) months, at the second futility analysis (60% of planned events), there were 143 deaths, 70 CROSS and 73 MAGIC/FLOT arm, with 3-year estimated survival probability of 56% (95% CI 47,64) and 57% (95% CI 48,65), respectively [(HR 1.02 (95%CI. 0.74-1.42))]. Based on the absence of futility evidenced in this data the DSMB recommended closure of recruitment in December 2020. Conclusions: This RCT reveals no evidence that peri-operative chemotherapy is unacceptably inferior to multimodal therapy, notwithstanding greater proxy markers of local tumour response in the CROSS arm. Oncologic and operative outcomes were consistent with optimum modern benchmarks. These data strongly suggest non-inferiority and support equipoise in decision making in modern practice.

High-dose versus standard-dose twice-daily thoracic radiotherapy for patients with limited stage small-cell lung cancer: an open-label, randomised, phase 2 trial. Lancet Oncol 2021; 22:321-331. [PMID: 33662285 DOI: 10.1016/s1470-2045(20)30742-7] [Citation(s) in RCA: 54] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 11/22/2020] [Accepted: 12/01/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND Concurrent chemoradiotherapy is standard treatment for limited stage small-cell lung cancer (SCLC). Twice-daily thoracic radiotherapy of 45 Gy in 30 fractions is considered to be the most effective schedule. The aim of this study was to investigate whether high-dose, twice-daily thoracic radiotherapy of 60 Gy in 40 fractions improves survival. METHODS This open-label, randomised, phase 2 trial was done at 22 public hospitals in Norway, Denmark, and Sweden. Patients aged 18 years and older with treatment-naive confirmed limited stage SCLC, Eastern Cooperative Oncology Group (ECOG) performance status 0-2, and measurable disease according to the Response Evaluation Criteria in Solid Tumors version 1.1 were eligible. All participants received four courses of intravenous cisplatin 75 mg/m2 or carboplatin (area under the curve 5-6 mg/mL × min, Calvert's formula) on day 1 and intravenous etoposide 100 mg/m2 on days 1-3 every 3 weeks. Participants were randomly assigned (1:1) in permuted blocks (sized between 4 and 10) stratifying for ECOG performance status, disease stage, and presence of pleural effusion to receive thoracic radiotherapy of 45 Gy in 30 fractions or 60 Gy in 40 fractions to the primary lung tumour and PET-CT positive lymph node metastases starting 20-28 days after the first chemotherapy course. Patients in both groups received two fractions per day, ten fractions per week. Responders were offered prophylactic cranial irradiation of 25-30 Gy. The primary endpoint, 2-year overall survival, was assessed after all patients had been followed up for a minimum of 2 years. All randomly assigned patients were included in the efficacy analyses, patients commencing thoracic radiotherapy were included in the safety analyses. Follow-up is ongoing. This trial is registered at ClinicalTrials.gov, NCT02041845. FINDINGS Between July 8, 2014, and June 6, 2018, 176 patients were enrolled, 170 of whom were randomly assigned to 60 Gy (n=89) or 45 Gy (n=81). Median follow-up for the primary analysis was 49 months (IQR 38-56). At 2 years, 66 (74·2% [95% CI 63·8-82·9]) patients in the 60 Gy group were alive, compared with 39 (48·1% [36·9-59·5]) patients in the 45 Gy group (odds ratio 3·09 [95% CI 1·62-5·89]; p=0·0005). The most common grade 3-4 adverse events were neutropenia (72 [81%] of 89 patients in the 60 Gy group vs 62 [81%] of 77 patients in the 45 Gy group), neutropenic infections (24 [27%] vs 30 [39%]), thrombocytopenia (21 [24%] vs 19 [25%]), anaemia (14 [16%] vs 15 [20%]), and oesophagitis (19 [21%] vs 14 [18%]). There were 55 serious adverse events in 38 patients in the 60 Gy group and 56 serious adverse events in 44 patients in the 45 Gy group. There were three treatment-related deaths in each group (one neutropenic fever, one aortic dissection, and one pneumonitis in the 60 Gy group; one thrombocytic bleeding, one cerebral infarction, and one myocardial infarction in the 45 Gy group). INTERPRETATION The higher radiotherapy dose of 60 Gy resulted in a substantial survival improvement compared with 45 Gy, without increased toxicity, suggesting that twice-daily thoracic radiotherapy of 60 Gy is an alternative to existing schedules.

Abstract
OBJECTIVES To evaluate intrafractional fiducial marker position variations during stereotactic body radiotherapy (SBRT) in patients treated for liver metastases in visually guided, voluntary deep inspiration breath-hold (DIBH). METHODS 10 patients with implanted fiducial markers were studied. Respiratory coaching with visual guidance was used to ensure comfortable voluntary breath-holds for SBRT imaging and delivery. Three DIBH CTs were acquired for treatment planning. Pre- and post-treatment CBCTs were acquired for each of the three treatment fractions. Per-fraction marker position was evaluated on planar 2D kV images acquired during treatment fractions for 4 of the 10 patients. RESULTS The median difference in marker position was 0.3 cm (range, 0.0-0.9 cm) between the three DIBH CTs and 0.3 cm (range, 0.1 to 1.4 cm) between pre- and post-treatment CBCTs. The maximum intrafractional variation in marker position in craniocaudal (CC) direction on planar kV images was 0.7 to 1.3 cm and up to 1.0 cm during a single DIBH. CONCLUSION Difference in marker position of up to 1.0 cm was observed during a single DIBH despite use of narrow external gating window and visual feedback. Stability examination on pre-treatment DIBH CTs was not sufficient to guarantee per-fraction stability. Evaluation of differences in marker position on pre- and post-treatment CBCT did not always reveal the full magnitude of the intrafractional variation. ADVANCES IN KNOWLEDGE To increase treatment accuracy, it is necessary to apply real-time monitoring of the tumour or a reliable internal surrogate when delivering liver SBRT in voluntary DIBH.

Abstract
INTRODUCTION Oncological treatment of lung cancer has been available in Greenland since 2004. We evaluated patient characteristics and survival rates for the first six years of local lung cancer treatment. METHODS From September 2004 to August 2010, a total of 173 patients with lung cancer were referred to treatment at Queen Ingrid's Hospital. On 1 February 2014, treatment results, survival, and prognostic variables were analysed. RESULTS The mean age at diagnosis was 63 years. Non-small cell lung cancer (NSCLC) was diagnosed in 145 patients (84%); 56% had squamous cell carcinoma, 34% had adenocarcinoma, 2% had large cell carcinoma and 8% had NSCLC not otherwise specified (NOS). In all, 28 (16%) had small cell lung cancer. A total of 142 patients (82%) received treatment; 20 underwent surgery (ten stage Ib, one stage IIa, five stage IIb, four stage IIIa); palliative chemotherapy was given to 122 of the 142 treated patients (86%). Of these, 36 patients (30%) received second-line chemotherapy.The median survival of patients undergoing primary lobectomy/pneumonectomy, palliative chemotherapy, and no treatment was 76.3 months, 11.8 months, and 2.0 months, respectively (p < 0.0001). CONCLUSION Evaluation of the first six years of lung cancer treatment in Greenland revealed a disease incidence and survival comparable to those found in the Nordic countries. To further decrease mortality from lung cancer, health-care resources should continue to be allocated to the prevention and treatment of lung cancer in Greenland. FUNDING not relevant.

Abstract
PURPOSE To determine if the level of apolipoprotein A1, hepcidin, transferrin, inter-α trypsin IV internal fragment, transthyretin (TT), connective-tissue activating protein 3 (CTAP3), serum amyloid A1, β-2 microglobulin (B2M) might have impact on overall and progression-free survival for ovarian cancer (OC) patients. EXPERIMENTAL DESIGN Serum from 150 OC patients was tested using SELDI-TOF-MS. RESULTS A proteomic prognostic index (xb-pro) was constructed using the regression coefficients based on inter-α trypsin IV internal fragment, B2M and TT. A multivariable Cox survival analysis including the xb-pro index showed that xb-pro (p<0.0001, HR=2.50, 95% CI: 1.65-3.79), residual tumor after primary surgery (p=0.0005), age (p=0.01) and chemotherapy (p=0.0002) are of independent prognostic value for overall survival. International Federation of Gynecology and Obstetrics stage, performance status, histological type of tumor and serum CA125 were found of no independent value. A proteomic index (xb-pfs) based on B2M and CTAP3 was found to predict progression-free survival (xb-pfs: p=0.008, HR=1.77, 95% CI: 1.17-2.70 together with type of surgery, age and chemotherapy. CONCLUSIONS AND CLINICAL RELEVANCE We found an index with three proteomic biomarkers (xb-pro) to be of independent prognostic value for overall survival and an index with two proteomic biomarkers (xb-pfs) with evidence of independent prognostic value for progression-free survival.

Abstract
INTRODUCTION In patients with advanced ovarian cancer undergoing preoperative PET/CT, we investigated the prognostic value of SUV in the primary tumor and we evaluated the value of SUV for predicting incomplete primary cytoreduction (macroscopic residual tumor). MATERIAL AND METHODS From September 2004 to August 2007, 201 consecutive patients with a pelvic tumor and a Risk of Malignancy Index (RMI) > 150 based on serum CA-125, ultrasound examinations and menopausal state, underwent PET/CT within two weeks prior to standard surgery/debulking of a pelvic tumor. At two-year follow-up (August 15, 2009) the association between SUV and overall survival/cytoreductive result were analyzed in 60 ovarian cancer patients (58 stage III and two stage IV). RESULTS At inclusion median age was 62 years (range 35-85 years); 97% (58/60) had a performance status ≤2; 42% (25/60) underwent complete debulking (no macroscopic residual tumor); median SUV(max) was 13.5 (range 2.5-39.0). Median follow-up was 30.2 months. At follow-up 57% (34/60) were alive and 43% (26/60) had died from ovarian cancer. SUV(max) in patients alive was not statistically different from SUV(max) in dead patients (p=0.69), and SUV(max) was not correlated with the amount of residual tumor after surgery (p=0.19). Using univariate Cox regression analysis, residual tumor was a significant prognostic variable (p=0.001); SUV(max) was not a statistically significant prognostic variable (p=0.86). DISCUSSION FDG uptake (SUV(max)) in the primary tumor of patients with advanced ovarian cancer was not a prognostic variable and the FDG uptake did not predict complete cytoreduction after primary surgery. Future prospective clinical trials will need to clarify if other PET tracers can serve as prognostic variables in ovarian cancer.

The objective of this prospective study was to evaluate CA-125 and a 7-marker panel as predictors of incomplete primary cytoreduction in patients with stage III/IV ovarian cancer (OC). From September 2004 to January 2008, serum from 201 patients referred to surgery for a pelvic tumor was analyzed for CA-125. In addition, serum was analyzed for 7 biomarkers using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry. These biomarkers were combined into a single-valued ovarian-cancer-risk index (OvaRI). CA-125 and OvaRI were evaluated as predictors of cytoreduction in 75 stage III/IV patients using receiver operating characteristic curves.Complete primary cytoreduction (no macroscopic residual disease) was achieved in 31% (23/75) of the patients. The area under the receiver operating characteristic curve was 0.66 for CA-125 and 0.75 for OvaRI.The sensitivity and specificity of CA-125 for predicting incomplete cytoreduction were 71% (37/52) and 57% (13/23), respectively (P = 0.04). The sensitivity and specificity of OvaRI for predicting incomplete cytoreduction were 73% (38/52) and 70% (16/23), respectively (P = 0.001). In conclusion, CA-125 and an index of 7 biomarkers were found to be predictors of cytoreduction. However, future studies of biomarkers are anticipated to promote early diagnosis and provide prognostic information to guide treatment of OC patients. In addition, new biomarkers might also play a role in predicting outcome from primary surgery in OC patients.

Prediction of suboptimal primary cytoreduction in primary ovarian cancer with combined positron emission tomography/computed tomography--a prospective study. Gynecol Oncol 2007; 108:265-70.

Abstract
OBJECTIVE To prospectively identify combined PET/CT predictors of incomplete/suboptimal primary cytoreduction in advanced ovarian cancer. METHODS From September 2004 to March 2007, 179 patients with a Risk of Malignancy Index (RMI) >150 based on serum CA-125, ultrasound examinations and menopausal state, underwent PET/CT within 2 weeks prior to standard surgery/debulking of a pelvic tumor. Ten PET/CT features were identified and evaluated as predictors of cytoreduction in 54 patients with advanced ovarian cancer. RESULTS Complete cytoreduction (no macroscopic residual disease) was achieved in 35% and optimal cytoreduction (<1 cm residual disease) was achieved in 56%. Using univariate analysis, predictors of incomplete cytoreduction were large bowel mesentery implants (LBMI) (P<0.003), pleural effusion (P<0.009), ascites (P<0.009) and peritoneal carcinosis (P<0.01). LBMI (P<0.03) and ascites (P<0.05) were also predictors of suboptimal cytoreduction. Using multivariate analysis, LBMI was the only independent predictor of incomplete cytoreduction (P=0.004) and no predictor of suboptimal cytoreduction was found. CONCLUSION PET/CT predictors of cytoreduction were found. But they should not be used to withhold patients form primary cytoreductive surgery. We suggest PET/CT as a supplementary image modality prior to surgery in primary OC patients whenever accurate and comprehensive preoperative evaluation of primary tumor and metastases is desired.

Abstract
OBJECTIVES To prospectively evaluate the diagnostic value of combined PET/CT in detecting a malignant tumor in patients with no previous cancer history, presenting with a pelvic mass. METHODS From September 2004 to March 2006, 101 patients (median age=60 years, range=24-85 years) with a Risk of Malignancy Index (RMI)>150 based on serum CA-125, ultrasound examinations (US) and menopausal state, were referred to PET/CT within 2 weeks prior to standard surgery/debulking of a pelvic tumor. Histological specimens from 97 patients were evaluated and the histological diagnoses were compared to the PET/CT results to calculate the diagnostic value of PET/CT in differentiating between malignant and borderline/benign tumors. Four patients refrained from surgery or biopsy. RESULTS The average serum CA-125 in the 97 studied patients was 784 U/ml (range=22-9665 U/ml). PET/CT demonstrated areas of abnormally increased metabolic activity considered highly suspicious for malignant tumor in 60 patients (62%). In 37 patients (38%) the tumors were considered benign on PET/CT. Histopathology showed benign tumors in 40 patients and malignant tumors in 57 patients. The sensitivity and specificity for PET/CT in diagnosing a malignant pelvic tumor were 100% (57/57) and 92.5% (37/40), respectively (P<0.00005). CONCLUSION Combined PET/CT demonstrates high diagnostic value in identifying primary ovarian cancer in patients with a pelvic mass of unknown origin and RMI>150. We suggest PET/CT as the image modality of choice when US shows a pelvic tumor and additional information prior to surgery is needed.

Abstract
Palmar-plantar erythrodysesthesia (PPE, hand-foot syndrome) is a relatively frequent cutaneous toxicity related to antineoplastic treatment with e.g. fluorouracil, capecitabine, and liposomal doxorubicin. It usually presents as paresthesia and painful erythema of the palms and soles and may lead to ulceration of the skin. The symptoms are dose-dependent, and the condition may be dose-limiting. Two cases of chemotherapy-associated PPE are presented.

Abstract
This prospective study regarding the quality of care and treatment on an unlocked psychiatric ward had two purposes. Firstly, to examine selected elements of care and treatment by continuously registering these elements during the patients' admission and to examine by questionnaire the patients' satisfaction with these elements at the time of their discharge. Secondly to test this method as a means of conducting quality assurance on psychiatric wards. The study took place at the Copenhagen County Hospital Herlev, Psychiatric Department Y, Denmark. Twenty-eight patients admitted to the psychiatric ward between March 1, and May 31, 1993 were included in the study and follow-up at their discharge. We found the method to be very good at uncovering strengths and weaknesses of the practices of our daily clinical work.

Abstract
In a retrospective study we reviewed the findings from 106 oesophago-gastro-duodenoscopies performed on HIV-positive patients between 01.01.93 and 31.12.94. Forty percent had Candida esophagei, 12% had Cytomegalovirus, 4% had atypical mycobacteria, 2% had Kaposi's sarcoma and 6% had Helicobacter pylori. Twelve percent of the patients received the diagnosis AIDS. The average CD4-cell count was 91 x 10(6)/l. The endoscopi findings were abnormal in 88% of HIV infected patients with gastrointestinal symptoms.
