European Board Certification

What is the FEBS-SO Exam? Complete Guide for Surgical Oncology Candidates

The FEBS-SO is the premier European certification in surgical oncology. This guide covers everything a candidate needs to know before sitting the examination — structure, eligibility, subject areas, and how to prepare.

What is FEBS-SO?

FEBS-SO stands for Fellowship of the European Board of Surgery — Surgical Oncology. It is a supranational specialty certification issued jointly by the Union Européenne des Médecins Spécialistes (UEMS) Section of Surgery and the European Society of Surgical Oncology (ESSO). It represents the highest level of formal recognition for surgical oncology expertise within the European framework.

Unlike national board exams, FEBS-SO is designed to be recognized across European Union member states and associated countries, providing a common standard for surgical oncology competency independent of local training variations. Passing FEBS-SO signals to institutions, colleagues, and patients that a surgeon has been evaluated against a rigorous, harmonized European standard.

The examination is organized under the UEMS Division of Surgical Oncology and coordinated in partnership with ESSO, which maintains the core curriculum on which the exam is based. The ESSO Core Curriculum document defines competency domains, expected knowledge, and technical skills across all major tumor types managed by surgical oncologists.

Exam Format

The FEBS-SO examination consists of two sequential components, both of which must be passed to obtain the Fellowship:

Part 1 — Written Examination (MCQ)

  • Format: 60 multiple-choice questions, single best answer from 5 options
  • Duration: 120 minutes (2 hours)
  • Scoring: No negative marking; one mark per correct answer
  • Pass mark: Determined by the Standard Setting Committee using modified Angoff method
  • Delivery: Paper-based or computer-based, at designated ESSO/UEMS centres

Part 2 — Oral Examination

  • Format: Structured oral examination with at least two examiners
  • Content: Clinical case discussion, management decisions, guideline application
  • Duration: Approximately 30–45 minutes
  • Timing: Typically held at the ESMO Congress in November
  • Prerequisite: Must pass Part 1 before sitting Part 2

The written examination is typically held in April. Candidates who fail Part 1 may resit in subsequent examination cycles. Candidates who pass Part 1 but fail Part 2 are generally permitted to resit the oral examination without retaking the written paper, subject to the current regulations published by the UEMS Section of Surgery.

Eligibility Requirements

To be eligible for FEBS-SO, candidates must satisfy criteria in three domains:

  • 1. Specialist qualification in surgery: Candidates must hold a Certificate of Completion of Training (CCT), or the national equivalent, in General Surgery or a surgical subspecialty recognized by the relevant national authority. This corresponds to completion of a full surgical residency.
  • 2. Subspecialty training in surgical oncology: Documented fellowship or equivalent structured experience in surgical oncology, typically a minimum of 12 months in a recognized unit with appropriate case volume across the principal tumor types in the ESSO Core Curriculum.
  • 3. ESSO membership or sponsorship: Candidates must be active members of ESSO or be sponsored by an ESSO member. Proof of participation in oncology-related activities (meetings, publications, or multidisciplinary tumor boards) may be required.

Candidates are advised to verify the current eligibility criteria directly with the UEMS Section of Surgery, as requirements may be updated between examination cycles.

Topic Areas

The FEBS-SO exam covers all major tumor types within the scope of surgical oncology practice. Based on the ESSO Core Curriculum, the principal topic domains are:

Breast Cancer

Staging, surgical techniques (BCS, mastectomy, oncoplastic), axillary management, neoadjuvant indications.

Melanoma, Skin and Endocrine Tumors

Melanoma staging and surgery, SLN biopsy, thyroid/parathyroid/adrenal oncology.

Colorectal and Peritoneal Malignancy

Colon and rectal cancer surgery, TME principles, peritoneal surface malignancy, CRS and HIPEC.

Upper GI and Esophagogastric

Esophageal and gastric cancer staging, Ivor Lewis, total gastrectomy, multimodal treatment.

Hepatopancreatobiliary (HPB)

Liver resection, pancreaticoduodenectomy, cholangiocarcinoma, HCC — indications and techniques.

Soft Tissue Sarcoma

Retroperitoneal and extremity sarcoma, compartmental resection, margin principles, GIST.

General Oncology Principles

Tumor biology, staging systems (TNM/AJCC 8th ed.), neoadjuvant/adjuvant therapy, MDT function.

Guidelines Tested

Questions in FEBS-SO are written to reflect current evidence-based practice as codified in major international guidelines. Candidates should be familiar with:

  • ESMO Clinical Practice Guidelines — primary reference for European practice across all tumor types
  • NCCN Guidelines — used as supplementary reference, particularly where ESMO is silent
  • ESSO Core Curriculum — defines the competency framework; essential reading for syllabus mapping
  • PSOGI Consensus — peritoneal surface oncology (CRS/HIPEC indications and technique)
  • EORTC and BJS consensus statements — sarcoma surgery, liver resection, margin standards
  • AJCC Cancer Staging Manual, 8th Edition — TNM classification for all tumor types

Exam Dates and Application

The FEBS-SO written examination is typically held in April each year. The oral examination follows in November, coinciding with the annual ESMO Congress. Applications open several months before each sitting, and candidates should monitor the ESSO and UEMS Section of Surgery websites for the precise timeline.

Application requires submission of documentation proving specialty qualification, surgical oncology training log, ESSO membership status, and payment of the examination fee. All submissions are reviewed by the FEBS-SO Examination Committee before candidacy is confirmed.

Why FEBS-SO Matters

For surgical oncologists practising in Europe, FEBS-SO provides a credential that transcends national boundaries. It is the only supranational European qualification specifically for surgical oncology — comparable in function to the ABS-CGSO in the United States — and is increasingly referenced by institutions when evaluating candidates for senior surgical oncology posts.

Beyond institutional recognition, FEBS-SO preparation itself is valuable. The process of systematically working through the ESSO Core Curriculum, reviewing ESMO guidelines across all tumor types, and practising structured clinical reasoning produces surgeons who are more consistent, more current, and more defensible in their decision-making than those who do not engage with formal certification.

The oral examination component adds a further dimension absent from written-only boards: candidates must not only know the correct answer but demonstrate the clinical reasoning process that leads to it — which is precisely what multidisciplinary tumor boards and institutional grand rounds require in practice.

How SurgBoardsQ&A Helps You Prepare

SurgBoardsQ&A contains 5,278 questions mapped to the FEBS-SO syllabus, organized by tumor type and ESSO Core Curriculum domain. Each question carries:

  • A detailed explanation referencing the specific ESMO or NCCN guideline section
  • Difficulty grading aligned with FEBS-SO exam complexity
  • Board tag indicating FEBS-SO relevance
  • Teaching point extracted from the landmark trial or consensus statement
