Goblet cell adenocarcinoma of the appendix: the decisions you may face

4 treatment settings, 4 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.

Expert pathology review with WHO 2019 grading; CT of chest, abdomen and pelvis; colonoscopy; tumour markers; no somatostatin receptor imaging is needed.

The options, in plain words

Histopathology means looking at cancer cells under a microscope, and immunohistochemistry stains them for specific proteins. Together they are still the foundation of every diagnosis.

  • Cheap, fast, universal
  • Companion diagnostic for most targeted drugs
CT (computed tomography)Standard of care

A CT scan is a fast 3D X-ray that shows the size and shape of tumours and whether they have spread.

  • Fast, ubiquitous
  • Sub-millimetre resolution
  • Standard for RECIST response
The evidence behind it

No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

The main trade-offs on record
  • Subjective scoring
  • Single-site sampling misses heterogeneity
  • Anatomic only; cannot distinguish scar from live tumour
  • Radiation dose
  • Poor for brain, marrow, and small peritoneal disease
Questions to ask about this decision
  1. Between Histopathology & immunohistochemistry and CT (computed tomography), which do you recommend for me, and what about my case would make you choose differently?
    Why: Guidelines list several reasonable options; the choice turns on details of your tumour, your health and your priorities.
  2. What is each option trying to achieve: cure, long control, or relief of symptoms, and over what time?
    Why: The aim shapes how much side effect and disruption is worth accepting.
  3. What happens if I delay, or decline this step for now? Is the decision reversible?
    Why: Some decisions can wait for a second opinion or a trial slot; others cannot. Knowing which is part of the choice.
  4. Does your recommendation follow the current guideline (NCCN Guidelines: Colon Cancer (appendiceal section)), and if it departs from it, why?
    Why: Departures from guidelines are sometimes right for an individual; they should be explained.
  5. For my situation (diagnosis), which of the standard options do you recommend and why?
    Why: Guideline options include: Expert pathology review with WHO 2019 grading; CT of chest, abdomen and pelvis; colonoscopy; tumour markers; no somatostatin receptor imaging is needed.

Right hemicolectomy with lymphadenectomy for all grades; oophorectomy considered in postmenopausal women; adjuvant FOLFOX or CAPOX for node-positive or grade 2 to 3 disease.

The options, in plain words

FOLFOX is the workhorse chemotherapy combination for bowel cancer, used after surgery to cure and in advanced disease as the backbone that targeted drugs are added to.

CAPOX pairs the oral fluoropyrimidine capecitabine with intravenous oxaliplatin as a pill-based alternative to FOLFOX. For low-risk stage III colon cancer three months after surgery works as well as six and halves nerve damage; it is also standard in gastric cancer, with hand-foot syndrome as its price.

The evidence behind it

No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

The main trade-offs on record

No side-effect rates or interaction flags are recorded for these options yet. The side-effect lookup and interaction checker cover the products that have them.

Questions to ask about this decision
  1. Between FOLFOX (5-FU, leucovorin, oxaliplatin) and CAPOX (capecitabine, oxaliplatin), which do you recommend for me, and what about my case would make you choose differently?

    Why: Departures from guidelines are sometimes right for an individual; they should be explained.
  5. For my situation (localised disease), which of the standard options do you recommend and why?
    Why: Guideline options include: Right hemicolectomy with lymphadenectomy for all grades; oophorectomy considered in postmenopausal women; adjuvant FOLFOX or CAPOX for node-positive or grade 2 to 3 disease.
  6. Am I a candidate for FOLFOX (5-FU, leucovorin, oxaliplatin), CAPOX (capecitabine, oxaliplatin), and what side effects should I expect?
    Why: Knowing the expected toxicities helps you plan work, family, and supportive care.

Other settings

Peritoneal metastases

2 options

Cytoreductive surgery with HIPEC in fit patients with limited disease, with perioperative systemic chemotherapy.

The options, in plain words

Washing the abdominal cavity with heated chemotherapy during surgery to kill microscopic peritoneal deposits.

  • High local concentration

FOLFOX is the workhorse chemotherapy combination for bowel cancer, used after surgery to cure and in advanced disease as the backbone that targeted drugs are added to.

The evidence behind it

No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

The main trade-offs on record
  • Morbidity, centre expertise
  • Mixed trial results

FOLFOX or CAPOX, then FOLFIRI, as for colorectal adenocarcinoma; somatostatin analogues and platinum-etoposide are not used.

The options, in plain words

FOLFOX is the workhorse chemotherapy combination for bowel cancer, used after surgery to cure and in advanced disease as the backbone that targeted drugs are added to.

CAPOX pairs the oral fluoropyrimidine capecitabine with intravenous oxaliplatin as a pill-based alternative to FOLFOX. For low-risk stage III colon cancer three months after surgery works as well as six and halves nerve damage; it is also standard in gastric cancer, with hand-foot syndrome as its price.

FOLFIRI is the other backbone bowel-cancer chemotherapy, swapping oxaliplatin for irinotecan. Used first or second line and, since 2026, with the BRAF combination.

How to read this page. Options and results come from OnCo records with their sources; the settings are the standard-of-care rows on the cancer page, and the lines of therapy are on the sequencing grid. Where a setting names one path, the choice is usually about timing, trials and where to be treated: see expert centres. OnCo is orientation, not medical advice.
