“An odd disposition of tumours” – less common metastases in Small Intestine and Pancreatic NETs

“An odd disposition of tumours” – less common metastases in Small Intestine and Pancreatic NETs

Every day is a learning day in NET! When I was diagnosed in 2010, my Oncologist sent me for a specialist scan that would help confirm my staging definition and to document anything that might not have shown up on CT.  This was described as an Octreotide Scan (somatostatin receptor scintigraphy) (now mostly replaced by Somatostatin Receptor PET (SSTR PET) e.g. Ga68/Cu64). Lo and behold, the 3 day Octreotide scan lit up some odd places which seemed to be unconnected to my small intestine primary.  I was already stage IV due to the presence of liver metastases and this was…

Do we need a new model for Carcinoid Crisis in NETs?

Do we need a new model for Carcinoid Crisis in NETs?

Update January 2024Dr Rodney Pommier, a NET specialist surgeon in Oregon has been writing about the issue of carcinoid crisis for some years and has finally produced data which turns previous guidelines on their head. Clearly when it comes to (so called) carcinoid crisis, surgeons are at the sharp end of experience alongside their anaesthetist colleagues. The detail from the study sits behind a paywall but the conclusion is given and cited below. You can read the abstract here or click on the 'conclusion' section below. I again emphasise as I have done in the original publication of this research below, nothing…

Randomized Phase II Trial of Postoperative Adjuvant Capecitabine and Temozolomide Versus Observation in High-Risk Pancreatic Neuroendocrine Tumors (SWOG S2104)

Randomized Phase II Trial of Postoperative Adjuvant Capecitabine and Temozolomide Versus Observation in High-Risk Pancreatic Neuroendocrine Tumors (SWOG S2104)

What is SWOG S2104? A Randomized Phase II Trial of Postoperative Adjuvant Capecitabine and Temozolomide Versus Observation in High-Risk Pancreatic Neuroendocrine TumorsPancreatic neuroendocrine tumors (pNETS) account for about 1-2% of all the pancreas tumors for which resection is the only curative intent modality, however, despite surgery, many patients will experience recurrence. Tumor size, positive lymph nodes and higher grade are prognostic factors for recurrence. The U.S. Neuroendocrine Tumor Study Group published a predictive score (Zaidi score but also see inclusion criteria) demonstrating that tumors with a score ≥6 had a 33% likelihood of recurrence by 24 months. Furthermore, it is…

FDA Accepts New Drug Application for Generic Lutetium Lu 177 Dotatate (177Lu-PNT2003) in GEP-NETs

Breaking News.  We have generic somatostatin analogues, generic targeted therapy, and I guess it was only a matter of time until we got generic PRRT (Radioligand Therapy) e.g. generic Lutetium Lu 177 dotatate.  This news begins that process which is also based on a clinical trial which took place in Canada (195 participants) and which now appears to be complete.  The announcement comes from US but if this is realised, you can expect it to be available in many other countries and continents where there is a market.  This may even drive down prices and/or increase availability.  The FDA has…

Midgut neuroendocrine tumor patients have a depleted gut microbiome with a discriminative signature

Midgut neuroendocrine tumor patients have a depleted gut microbiome with a discriminative signature

What is the gut microbiome?   According to Cleveland Clinic, your gut microbiome is a microscopic world within the world of your larger body. The trillions of microorganisms that live there affect each other and their environment in various ways. They also appear to influence many aspects of your overall health, both within your digestive system and outside of it.  If you read their summary here, you can understand some of the implications of this study. However, as the study concluded, midgut NET patients have an altered gut microbiome which could suggest a role in NET development and provide novel targets…

Meet Edison® Histotripsy System – powerful bubbles

Please read this before asking questionsHistotripsy is a new treatment, but it's an ablative technique rather than a drug.  It can be equated to liver embolization or conventional tumour ablation but uses what would appear to be a more effective targeted therapy.  It's early days, the fact that it has been approved by FDA (see wording below) is about all we know but this blog will be kept live.  I get asked a lot of questions but some of the detail NET patients tend to ask is simply not available to me.  1.

Neuroendocrine Cancer Clinical Trial – Lutetium-177Lu (Satoreotide)

Neuroendocrine Cancer Clinical Trial – Lutetium-177Lu (Satoreotide)

What is Satoreotide? It's an agonist treatment. i.e. a 'next generation' radiologand for Peptide receptor radionuclide therapy (PRRT) or more specifically the radiopharmaceutical that binds to both activated and unactivated somatostatin receptors which are upregulated on these tumours. There is far higher binding via this mechanism than standard octreotate. The technical name of the radiopharmaceutical is Satoreotide tetraxetan lutetium-177 (author's note, I'm guessing but it could be a variant of Lanreotide). Somatostatin type 2 (SST2) receptor is overexpressed in many around 80% of NETs, some NEC and in certain hard-to-treat cancers such as small cell lung cancer (SCLC) and neuroblastoma,…

First and only FDA-cleared, fully automated chromogranin A assay

First and only FDA-cleared, fully automated chromogranin A assay

There has been controversy about the utility of Chromogranin A for many years now.  Specialists have been critical about its use but to be fair even those less critical still confirm that alone it would not be trusted to formally diagnose Neuroendocrine Cancer.  That said, it was still controversial when certain US guidelines were updated to recommend it is not regularly tested.  It's well known for being a sensitive but non-specific marker for most tumours of Neuroendocrine type, the non-specificity is mostly due to the other conditions, some of which are highly prevalent in many countries, including but not limited to…

Lung cancer diagnosed early because of new tool

Lung cancer diagnosed early because of new tool

I'm a believer in science overtaking mortality figures and there is evidence of that already happening when you read the latest survival figures. But too many are still succumbing to this killer disease.  I also believe that artificial intelligence (AI) has the potential to help. Even with cancers of the lung, where known causes are heavily linked to death rates, are decreasing but that is mainly due to preventative measures such as stopping smoking.  However, not all cancers of the lung are caused by smoking. Most low-grade Lung NETs is a good example, there are others. I've had a flurry…

Just about everyone knows who Steve Jobs is but not many people have heard of Reed Jobs.  Clearly a relative and is actually his son.  Now aged 31, he wants to get into the cancer business via a venture capitalist initiative.  The headline below looks great but it means cancer, not just Neuroendocrine Cancer (note the use of Steve Jobs' actual diagnosis).I first heard about this and switched off after the news article stated that Steve Jobs had Pancreatic Cancer. Don't get me wrong, I strongly believe that Pancreatic Cancer needs lots of attention and lots of funding and research. …

A tumour-finding probe improves the ‘effectiveness of surgery in Gastrointestinal neuroendocrine tumours

A tumour-finding probe improves the ‘effectiveness of surgery in Gastrointestinal neuroendocrine tumours

A major challenge that cancer surgeons face currently is that there are no reliable methods to identify the tissue type during surgery (other than fast tracking tissue sampling). The surgical procedures, therefore, rely extensively on the experience and judgment of the surgeon to decide on how much tissue to remove around the tumor margins.  Sometimes this can result in the removal of excessive healthy tissue. On the other hand, not removing some tumour cells can often need a follow-up surgery to remove residual cancer tissue. This just adds to patient morbidity and long-term detrimental effects on the patient’s outcome. The use…

Many people with a Gastric NET will already have acid reflux related issues and many will be taking medications such as proton pump inhibitors.  But I was surprised to find there was not an approved targeted medication that…

A tribute to the life and legacy of Miranda Filmer

A tribute to the life and legacy of Miranda Filmer

It's true to say that Neuroendocrine Cancer is an older person's disease, the epidemiology is clear on that.  But I do see many young people diagnosed. In my own experience and observation, I normally see three main scenarios with younger people; an incidentally discovered appendiceal NET after appendicitis, someone with hereditary NET (e.g. Multiple Endocrine Neoplasia (MEN)) or an aggressive version of the disease.  There are others but I find these are the most common scenarios I see in younger people.  For me personally, as a father and a grandfather, it's often heart-breaking to read these stories. I wanted to…

Belzutifan for the Treatment of Advanced Pheochromocytoma/Paraganglioma (PPGL), Pancreatic Neuroendocrine Tumor (pNET), or Von Hippel-Lindau (VHL) Disease-Associated Tumors

What is von Hippel-Lindau disease (VHL)?Von Hippel-Lindau disease (VHL) is an autosomal dominant disease that can predispose individuals to multiple neoplasms. Germline pathogenic variants in the VHL gene predispose individuals to specific types of benign tumors, malignant tumors, and cysts in many organ systems. These include central nervous system hemangioblastomas; retinal hemangioblastomas; clear cell renal cell carcinomas and renal cysts; pheochromocytomas, cysts, cystadenomas, and neuroendocrine tumors of the pancreas; endolymphatic sac tumors; and cystadenomas of the epididymis. What is Belzutifan (Welireg)?It is an oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor. As an inhibitor of HIF-2α, belzutifan reduces transcription and expression of HIF-2α target genes associated with cellular proliferation, angiogenesis and…

Cancer Ablation

Cancer Ablation

What is Cancer Ablation? This is a minimally invasive surgical method to treat solid cancers. Special probes are used to “burn” or “freeze” cancers. Computed Tomography (CT), Ultrasound (US) or Magnetic Resonance Imaging (MRI) is used to guide and position the needle probe into the tumour. This requires only a tiny hole, usually less than 3 mm via which the probe is introduced. When the probe is within the cancer it is attached to a generator which “burns” or “freezes” the cancer.  “Burning” refers to increasing the temperature of the tumour to such a level that cancer cells die. This…

EUS Guided Ablation for small pancreatic NETs (Less than 2cm)

To burn or not to burn?I once wrote a post about Pancreatic NET "to cut or not to cut".  You can read that here.  Surgery for small pancreatic NETs remains controversial with most guidelines and study guidelines recommending surveillance for small primary tumours less than 2cm.  There are exceptions to that, e.g. preventative surgery if the tumour is threatening important vessels and for functional cases where the surgery is palliative in nature.  Contrast that against some patient perspectives where they just want it cut out (and some will 'surgeon-shop' until they find someone who will).Most pancreatic NET are lower grades…

A multicentre validation of the NETPET score (Dual [68Ga]DOTATATE and [18F]FDG PET/CT in patients with metastatic GEPNENs

A multicentre validation of the NETPET score (Dual [68Ga]DOTATATE and [18F]FDG PET/CT in patients with metastatic GEPNENs

Background It's normally the case that the higher the grade/Ki67 in Neuroendocrine Neoplasms (NENs), the less likely the tumours will have somatostatin receptors and therefore be able to take advantage of somatostatin receptor PET (SSTR PET) as the gold standard in nuclear imaging.  This is why most grade 3 NENs will receive [18F]FDG PET/CT which finds glycolytic activity in the tumour and predicts an aggressive disease course and normally a higher histological grade. It can also add to prognostic outcomes, which in turn can add to therapy choice decisions. There is an overlap though, particularly with the recognition of well-differentiated…

Stereotactic body radiation therapy (SBRT) in the treatment of Neuroendocrine Neoplasms

Stereotactic body radiation therapy (SBRT) in the treatment of Neuroendocrine Neoplasms

What is Stereotactic Body Radiation Therapy (SBRT)? External beam radiotherapy has been around for a while. But the next generation equipment and techniques are gradually being deployed.   It's a confusing area with many synonyms which I found when I wrote about the subject in a treatment summary for patients.  Some of the sub-components/synonyms may be familiar to you and are often used interchangeably with SBRT; but are actually a brand name (e.g.Cyberknife) or a type (e.g. Proton Beam). You will not find SBRT mentioned in any Neuroendocrine Neoplasms (NENs) guidelines and that's because it is not a "standard of care"…

New test of pancreatic cysts to help with cancer detection

New test of pancreatic cysts to help with cancer detection

With NETs, particularly pancreatic NETs, due to a lack of efficient prognostic markers, it is difficult to identify which cases are more likely to metastasise than others. Identifying whether cysts will turn cancerous is also another area requiring a screening program as a standard of care to monitor.   Molecular testing is advancing and this test I'm reporting here looks like good news in the case of assessing the risks of pancreatic cysts.  Pancreatic cysts are common. For example, up to 15% of the U.S. population will develop a pancreatic cyst at some point in their lives. Most of these cysts…

Prospective Phase II Trial of Prognostication by 68Ga-NOTA-AE105 uPAR PET in Patients with Neuroendocrine Neoplasms: Implications for uPAR-Targeted Therapy

Summary A novel PET radiotracer can accurately assess the presence of a biomarker that indicates the level of tumor aggressiveness in neuroendocrine neoplasms (NENs). According to research published in the September issue of The Journal of Nuclear Medicine, the detection of the biomarker provides useful information for physicians to provide personalized care for patients with NENs and may also serve as a potential target for peptide radionuclide therapy (PRRT) for NEN patients.What is uPAR? Tumorigenesis (the production or formation of a tumour or tumours) is closely related to the loss of control of many genes.

Management of asymptomatic sporadic non-functioning pancreatic neuroendocrine neoplasms no larger than 2 cm: interim analysis of prospective ASPEN trial

Management of asymptomatic sporadic non-functioning pancreatic neuroendocrine neoplasms no larger than 2 cm: interim analysis of prospective ASPEN trial

One of the most controversial subjects in Neuroendocrine Neoplasms is the management of small non-functional (asymptomatic) pancreatic NETs (NF-PanNEN).  In the most general terms, surgery is not recommended in tumours less than 2cm.  Allowances are made for those who are functional (i.e. symptomatic with one of several syndrome possibilities) or where the tumour is threatening important vessels (i.e. pre-emptive surgery).  Normally watching and waiting is recommended.  I wrote more detail in an earlier blog - Pancreatic Neuroendocrine Tumours - to cut or not to cut Some patients opt (or push for) a non-guideline surgery regardless and as one other patient…

Prospective phase II trial of [68Ga]Ga-NODAGA-E[c(RGDyK)]2 PET/CT imaging of integrin  for prognostication in patients with neuroendocrine neoplasms

Prospective phase II trial of [68Ga]Ga-NODAGA-E[c(RGDyK)]2 PET/CT imaging of integrin for prognostication in patients with neuroendocrine neoplasms

August 25, 2022 -- A new gallium-68 PET radiotracer appears effective for predicting higher risk of disease progression and mortality in patients with neuroendocrine tumors, according to a study published August 18 in the Journal of Nuclear Medicine. Conclusion: Tumor lesion uptake of 68Ga-NODAGA-E[c(RGDyK)]2 was evident in patients with all grades of NEN. High uptake was associated with a poorer prognosis. Further studies are warranted to establish if 68Ga-NODAGA-E[c(RGDyK)]2 PET/CT may become a prediction tool for identification of patients eligible for treatments targeting integrin αvβ3. Why is this different to regular Ga68 Dotatate?  In the simplest of terms, Ga68 Dotatate is targeting somatostatin receptors which…

Curtis Crump: “If I’m going down, it won’t be without a fight.”

Curtis Crump: “If I’m going down, it won’t be without a fight.”

Curtis Crump: Credit MD Anderson Cancer Center Curtis Crump has an amazing story to tell.  Given 6 months to live, he refused to accept that prognosis and looked elsewhere. He found a top hospital that directed him to an established clinical trial of immunotherapy. Curtis has a high grade aggressive type of Neuroendocrine Cancer called Neuroendocrine Carcinoma (with a Colon primary).  The immunotherapy has some effect to the point that he was able to have surgery, a treatment option not always available to poorly differentiated Neuroendocrine Carciomas. His story is relevant to many people's experiences across the broad spectrum of…

Survival Outcomes in Metastatic Gastroenteropancreatic Neuroendocrine Tumor Patients receiving Concomitant 225Ac-DOTATATE Targeted Alpha Therapy and Capecitabine: A Real-world Scenario Management Based Long-term Outcome Study

Survival Outcomes in Metastatic Gastroenteropancreatic Neuroendocrine Tumor Patients receiving Concomitant 225Ac-DOTATATE Targeted Alpha Therapy and Capecitabine: A Real-world Scenario Management Based Long-term Outcome Study

Introduction I've written about both 225Ac-DOTATATE targeted alpha therapy (TAT) and Capecitabine before but never as a concomitant pair (combo). So, when this Indian study came up on my radar, I felt it was a useful addition to my website adding to my existing targeted alpha therapy portfolio of information.  India appears to be using more of this type of PRRT than any other country. Read more about targeted alpha therapy by clicking here or on the photo below. Read more about Capecitabine (combo with Temozolomide) by clicking here or on the photo below. The abstract from the Indian study…

Assessment of Clinical Response Following Atezolizumab and Bevacizumab Treatment in Patients With Neuroendocrine Tumors: A Nonrandomized Clinical Trial

Assessment of Clinical Response Following Atezolizumab and Bevacizumab Treatment in Patients With Neuroendocrine Tumors: A Nonrandomized Clinical Trial

BackgroundWell differentiated NETs have been described as an "immunological desert" in recent years mainly due to the poor response rate data coming out of clinical trials of immunotherapy drugs.  Poorly differentiated NEC has favoured better but mainly in the more obscure types.  Which is why these data of a combo treatment containing one immunotherapy drug caught my eye. What is atezolizumab?  It is a type of monoclonal antibody and a type of immune checkpoint inhibitor.  It's a Programmed cell death protein -1 (PD-1)/ Ligand 1 (PD-L1) inhibitor.  A drug that binds to the protein PD-L1 to help immune cells kill cancer…

Clinical Trial: Triapine and Lutetium Lu 177 Dotatate for Neuroendocrine Tumors

Clinical Trial: Triapine and Lutetium Lu 177 Dotatate for Neuroendocrine Tumors

What is PRRT? I'm guessing most of my readers know what Peptide Receptor Radiotherapy (PRRT) is.  But for those new to this field, read more here What is Triapine? Triapine is a ribonucleotide reductase (RNR) inhibitor, I.e. it helps repair DNA.  When I research this drug, I can see it is used in numerous examples of clinical trials in an anti-cancer setting alongside radiotherapy and chemotherapy, in many cancers. Triapine in NET There is currently a trial of Triapine with Lutathera (PRRT) (11 major US hospitals).  This study was testing the hypothesis that triapine is an effective radiation sensitizer that…

CAPTEM for Neuroendocrine Tumours

CAPTEM for Neuroendocrine Tumours

What is CAPTEM? Capecitabine is an oral drug used alone or with other drugs to treat certain types of colorectal cancer and breast cancer. It is also being studied in the treatment of other types of cancer including in combination with a second drug. Capecitabine is taken up by cancer cells and breaks down into fluorouracil, a substance that kills cancer cells. Xeloda is a type of antimetabolite. Also called Xeloda.Temozolomide is an oral drug used to treat adults with certain types of brain tumors. It is also being studied in the treatment of other types of cancer including in combination…

Clinical Trial:  Dostarlimab, anti–PD-1 monoclonal antibody in Neuroendocrine Carcinoma

Clinical Trial: Dostarlimab, anti–PD-1 monoclonal antibody in Neuroendocrine Carcinoma

BackgroundFollowing the Americal Society of Clinical Oncology (ASCO) conference in June 2022 (ASCO is the biggest Oncology event in the world), the media widely featured the results of the Phase 2 clinical trial of the drug Dostarlimab, an anti–PD-1 monoclonal antibody. The media often looks for headline-grabbing stories and this was one of them.  One UK TV outlet said they may have found the cure for cancer, which is a reckless statement when you look at the size and boundary of the clinical trial referenced.  The detail is, that this was a phase 2 trial for "rectal adenocarcinoma", but specifically…

Electronic Autoinjector for Somatuline® Autogel® / Somatuline® Depot (lanreotide)

Electronic Autoinjector for Somatuline® Autogel® / Somatuline® Depot (lanreotide)

Update 11th Jan 2024.  Ipsen decided to change the name for Somatuline Autogel to Lanreotide Ipsen.  Clearly to distinguish its product from the generics now rolling out.  Not seen similar yet for Somatuline Depot (US). An Electronic Autoinjector for Somatuline® Autogel® / Somatuline® Depot (lanreotide) - now that sounds exiting.  It doesn't seem that long since we got the new improved injection delivery system for the current model of Lanreotide.  I had to look at my blog articles for the announcement of that and was surprised it was way back in 2019.  It may be a shorter time period for many…
