Twenty-One Years of Colorectal Malignancies at a Palestinian Pathology Network: A Retrospective Analysis of 1,381 Cases (2005–2026)
This retrospective analysis of 1,381 colorectal malignancy cases from a Palestinian pathology network (2005–2026) reveals a rising incidence with a notably high burden of early-onset disease, a balanced sex ratio, and a predominance of left-sided adenocarcinomas, highlighting the urgent need for expanded registries and revised screening guidelines in the region.

Imagine the West Bank as a vast, bustling city where people occasionally get sick with a specific type of trouble in their digestive system called colorectal cancer. For the last 21 years, a team of medical detectives at Medicare Labs has been keeping a giant, digital "ledger" of every single case they've found.
This paper is the story of what they found in that ledger: 1,381 confirmed cases of this cancer, collected between 2005 and May 2026. Here is the story of their findings, told simply.
1. The Detective Work (How they found the cases)
Think of the lab's database as a massive library with over 14,000 books (medical records). The researchers didn't read every single page. Instead, they used a special "searchlight" (a computer filter) to find any book that mentioned words like "cancer," "tumor," or "colon."
Once they found a potential match, a human detective (a pathologist) double-checked it to make sure it was actually a primary cancer and not something else, like a benign polyp or a cancer that started elsewhere and spread there. After this careful filtering, they were left with the final list of 1,381 confirmed cases.
2. Who is getting sick? (The People)
- Men vs. Women: In many parts of the world, men get this cancer much more often than women (like a 3-to-2 ratio). But in this group, it was a perfectly balanced team. There were 699 men and 682 women. It was almost a 50/50 split, which is a bit of a surprise compared to Western countries.
- The Age Gap: The "average" patient was 60 years old. However, there was a shocking number of young people. About 1 in 5 patients (22.1%) were under 50. Some were even in their 30s or younger. The authors call this a "high early-onset burden," meaning young people are getting sick at a rate much higher than what is usually seen in Western countries.
3. Where is the trouble? (The Location)
- The "Left Side" Rule: If you imagine the colon as a long tube, the cancer was mostly found on the left side (the sigmoid colon and rectum). About 44% of the specific cases were here. This is different from some Western trends where the cancer is moving toward the right side.
- The "Unknown" Pile: A huge chunk of the cases (38.7%) were just labeled "Colon, NOS" (Not Otherwise Specified). Think of this as a detective finding a suspect but forgetting to write down which house they lived in. This happened because older reports didn't always specify the exact spot. Newer reports are much better at this.
4. What does the cancer look like? (The Type)
- The Usual Suspect: 9 out of 10 cases (90.8%) were a standard type called Adenocarcinoma. This is the "common criminal" of colorectal cancer.
- The Aggressive Villain: There were 34 cases of a rare, very aggressive type called Signet Ring Cell Carcinoma. The authors note this is important because these types of cancers are often found in younger people and might be linked to genetic issues that run in families.
- The Rare Ones: A tiny handful were other types, like lymphomas or neuroendocrine tumors, which are like "special forces" that need different treatment plans.
5. The Trend Over Time (The Timeline)
If you look at the numbers year by year, it looks like a steep hill:
- 2005: Only 1 case was recorded (the network was just starting).
- 2010s: The numbers climbed steadily as the lab network grew and more people were referred.
- The Pandemic Dip: In 2020, 2021, and 2022, the numbers dropped. This wasn't because people stopped getting cancer; it's because hospitals were overwhelmed, and people were afraid to go in for check-ups.
- The Bounce Back: By 2024 and 2025, the numbers shot up again, hitting a record high of 113 cases in 2025. The authors say this rise is likely a mix of the lab network getting bigger and the actual number of cases increasing.
6. What the Authors Say We Should Do
Based on this "ledger," the authors make three main suggestions:
- Check the Younger People: Since so many patients are under 50, they suggest doctors might need to start screening younger people than usual, or at least look very closely at anyone with symptoms under 50.
- Look for Genetic Clues: Because there are so many young patients and that specific "Signet Ring" type, they recommend testing every new cancer case for a specific genetic marker (called MMR/MSI). This could help find families at risk for hereditary cancer syndromes.
- Build a Better Map: They suggest turning this lab data into a formal, national "cancer registry" so they can track the disease better in the future.
The Bottom Line
This paper is the largest collection of colorectal cancer data ever published from the Palestinian territories. It tells us that while the cancer is mostly found on the left side and affects men and women equally, there is a growing and worrying trend of young people getting sick. The authors urge that we pay attention to these young patients and update our screening rules to match this new reality.
